This adaptability is valuable in both macro and micro-level analyses, helping to reveal larger patterns or fine-grained insights.<\/span><\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Characteristics_of_a_Ratio_Scale\"><\/span><strong>What Are the Characteristics of a Ratio Scale?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A ratio scale offers one of the most precise and versatile ways to measure data, with unique features that make it an integral part of surveys across various fields. Here are some of its characteristics:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>True Zero Point<\/b><span style=\"font-weight: 400;\">: Ratio scales have an absolute zero, which indicates the absence of the quantity being measured. For example, zero dollars means no money and zero weight means no weight. This true zero makes the scale highly meaningful, especially when assessing variables that can reach a baseline of zero.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Equal Intervals<\/b><span style=\"font-weight: 400;\">: Each unit on a ratio scale represents the same amount, so moving from 10 to 20 is the same incremental change as moving from 90 to 100. This consistency allows for precise comparisons and reliable analysis.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Flexibility with Mathematical Operations<\/b><span style=\"font-weight: 400;\">: Unlike other scales, ratio scales allow for addition, subtraction, multiplication, and division. This flexibility means you can perform in-depth analyses, from calculating averages to examining growth ratios, making it particularly useful for complex datasets.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Meaningful Ratios<\/b><span style=\"font-weight: 400;\">: Ratio scales enable statements like \u201ctwice as much\u201d or \u201chalf as much\u201d to be accurate and significant. For instance, 20 pounds is double 10 pounds, and 50 miles is half of 100 miles, offering real comparability across values.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Comprehensive Statistical Analysis<\/b><span style=\"font-weight: 400;\">: With ratio data, you can calculate averages, medians, standard deviations, and other statistical measures, allowing for a deeper understanding of trends and distributions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Wide Application<\/b><span style=\"font-weight: 400;\">: Ratio scales are ideal in fields that demand precise measurements, such as finance, health sciences, engineering, and social research. Examples of ratio data include age, income, distance, and time.<\/span><\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_Some_Popular_Ratio_Scale_Examples\"><\/span><strong>What Are Some Popular Ratio Scale Examples?\u00a0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Ratio scales are used in various fields to measure data where a true zero exists and equal intervals matter. Here are some practical <\/span><span style=\"font-weight: 400;\">ratio data examples<\/span><span style=\"font-weight: 400;\"> across various parameters:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Weight<\/b><span style=\"font-weight: 400;\">: Whether measured in pounds, kilograms, or grams, weight has a true zero (no weight) and allows meaningful comparisons. For instance, 40 pounds is twice as heavy as 20 pounds.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Height<\/b><span style=\"font-weight: 400;\">: Height measurements in inches, feet, or centimeters also use a ratio scale. Zero height would mean an absence of height, and comparisons like \u201ctwice as tall\u201d are meaningful.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Income<\/b><span style=\"font-weight: 400;\">: Annual income, measured in dollars or any currency, is a classic ratio scale example. With a true zero point, statements like \u201cearning double\u201d are accurate, allowing easy comparisons between income levels.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Distance<\/b><span style=\"font-weight: 400;\">: Distance measured in miles or kilometers has a zero point and allows for ratios. For instance, 50 miles is half the distance of 100 miles, which is essential in fields like geography and travel.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Age<\/b><span style=\"font-weight: 400;\">: Age, often measured in years, has a true zero and can be used to compare ratios (e.g., a 20-year-old is twice the age of a 10-year-old), making it ideal for demographics and market research.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Time<\/b><span style=\"font-weight: 400;\">: Time spent or duration (such as hours worked) is a ratio scale, with zero representing no time. Statements like \u201ctaking twice as long\u201d are meaningful, useful for productivity analysis and project planning.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Here are some sample questions you can use in a ratio scale survey.<\/span><\/p>\n<ol>\n<li><span style=\"font-weight: 400;\"> A ratio scale is used to gather data on age in a <\/span><a href=\"https:\/\/www.proprofssurvey.com\/blog\/market-research-survey\/\"><span style=\"font-weight: 400;\">market research survey<\/span><\/a><span style=\"font-weight: 400;\">, uses the scale as follows:<\/span><\/li>\n<\/ol>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Younger than 20<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">20-28<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">28-35<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">35-40<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Older than 40<\/span><\/li>\n<\/ul>\n<ol start=\"2\">\n<li><span style=\"font-weight: 400;\"> A ratio scale is used to figure out how much time people spend on video games.<\/span><\/li>\n<\/ol>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Less than 1 hour<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">1 to 2 hours<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">2 to 3 hours<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">More than 3 hours<\/span><\/li>\n<\/ul>\n<ol start=\"3\">\n<li><span style=\"font-weight: 400;\"> What is your weight in kgs?<\/span><\/li>\n<\/ol>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Less than 50 kgs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">51-60 kgs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">61-70 kgs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">71-80 kgs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">81-90 kgs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Above 90 Kgs<\/span><\/li>\n<\/ul>\n<ol start=\"4\">\n<li><span style=\"font-weight: 400;\"> What is your height in feet and inches?<\/span><\/li>\n<\/ol>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Less than 5 feet<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">5 feet 1 inch \u2013 5 feet 5 inches<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">5 feet 6 inches- 6 feet<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">More than 6 feet<\/span><\/li>\n<\/ul>\n<ol start=\"5\">\n<li><span style=\"font-weight: 400;\"> What is the number of minutes you work out each day?<\/span><\/li>\n<\/ol>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">20-30<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">30-45<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">45- 1 hour<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">More than 1 hour<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Advantages_of_Ratio_Scale\"><\/span><strong>What Are the Advantages of Ratio Scale<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The ratio scale\u2019s true zero, ability to support full arithmetic operations, and ease of comparison make it a valuable tool for gathering meaningful, detailed data. Let\u2019s look at some of its key advantages:<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>1. Precise Measurement:<\/b><span style=\"font-weight: 400;\"> Ratio scales offer the highest level of precision, allowing for accurate measurement of quantities with a true zero point.

Here\u2019s how to make the most of ratio data in your analysis:<\/span><\/p>\n<h3><b>1. Calculate Measures of Central Tendency<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Ratio data allows you to find the mean (average), median (middle value), and mode (most frequent value), helping you understand the central point of your data. The mean is commonly used for ratio data because it incorporates all values and provides a single representative number.<\/span><\/p>\n<h3><b>2. Use Measures of Dispersion<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">To understand the spread of ratio data, calculate the range, variance, and standard deviation. These measures indicate how much the data values differ from the mean, giving insights into variability and consistency within your dataset.<\/span><\/p>\n<h3><b>3. Apply Ratios and Proportions<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Ratio data enables comparisons like \u201ctwice as much\u201d or \u201chalf as much.\u201d For example, if analyzing income, you can compare different income groups directly or calculate growth rates and proportions to observe trends over time.<\/span><\/p>\n<h3><b>4. Perform Advanced Statistical Tests<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Ratio data supports both descriptive and inferential statistics. Common tests include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>T-tests<\/b><span style=\"font-weight: 400;\"> and <\/span><b>ANOVA<\/b><span style=\"font-weight: 400;\"> to compare group means and understand whether differences are statistically significant.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Correlation and Regression Analysis<\/b><span style=\"font-weight: 400;\"> to examine relationships between ratio variables (e.g., income and spending patterns).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Chi-square Tests<\/b><span style=\"font-weight: 400;\"> for frequency-based data, assessing if there\u2019s a relationship between categories in a dataset.<\/span><\/li>\n<\/ul>\n<h3><b>5. Visualize with Graphs and Charts<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Graphs like histograms, bar charts, and scatter plots are ideal for displaying ratio data. Histograms show data distribution, while scatter plots reveal patterns or relationships between two ratio variables, making insights easy to interpret visually.<\/span><\/p>\n<h3><b>6.

Segment and Compare Data<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Segmenting ratio data into groups (e.g., age groups, income brackets) allows for detailed analysis within specific categories. This approach is useful for examining differences across demographic segments or other groups within your dataset.<\/span><\/p>\n<h3><b>8. Conduct Multivariate Analysis<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">For more complex analyses, consider multivariate techniques to study multiple variables simultaneously. For example, in customer data, you could analyze age, income, and spending together to find patterns in buying behavior.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"When_to_Use_the_Ratio_Scale_Variable\"><\/span><strong>When to Use the Ratio Scale Variable<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The ratio scale is best used when measuring variables with a true zero point and can be compared through mathematical operations. Ratio scale variables are ideal for data that allows for precise comparisons of quantities, such as height, weight, distance, and age. Here\u2019s when you\u2019d typically want to use the ratio scale:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Absolute Zero Point<\/b><span style=\"font-weight: 400;\">: When your data has a clear zero point (e.g., 0 weight means no weight), allowing for meaningful statements about \u201cnone\u201d of a quantity.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Quantitative Comparisons<\/b><span style=\"font-weight: 400;\">: When you need to make statements about how much more or less of something exists (e.g., &#8220;twice as heavy&#8221; or &#8220;half as long&#8221;).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Mathematical Analysis<\/b><span style=\"font-weight: 400;\">: When your analysis requires the use of ratios, proportions, or other calculations that involve absolute differences and comparisons (e.g., average, standard deviation, or percentage increase).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Consistency Across Intervals<\/b><span style=\"font-weight: 400;\">: When you need consistent interval measures across a scale that can be multiplied or divided meaningfully, such as in physics or finance.<\/span><\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_the_Difference_Between_an_Interval_and_a_Ratio_Scale\"><\/span><strong>What Is the Difference Between an Interval and a Ratio Scale?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Interval and ratio scales are two of the four measurement scales that describe the attributes of quantitative scales.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These two scales are often confusing as ratio data possess all the properties of interval data, such as\u2014data should have numeric values, the distance between the two points is equal, etc., but zero is arbitrary in internal data, whereas in ratio data, zero is absolute.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Let\u2019s have a look at more differences between these two scales:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">1. The variable of the interval scale has a definite order, and the difference between them has meaning, but the ratio between them doesn\u2019t have any meaning. For example, increasing the temperature from 15 to 30 degrees Celsius doesn\u2019t mean it\u2019s twice as hot.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, both the difference and the ratio between the variables of the ratio scale have meaning. For example, if you increase weight from 10 kg to 20 kg, it\u2019s twice as heavy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">2. Another key difference between an internal scale and a ratio scale is that the ratio scale has a true zero, which means if a value is zero, it doesn\u2019t exist. For example, if you measure height as zero, then the height doesn\u2019t exist.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Whereas the interval scale may have zero but it\u2019s not absolute. For instance, if you measure height as zero, it exists. And even it can be negatives which is just another measurement on the interval scale.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">3, Statistical parameters such as multiplication and division have no meaning in interval scale variables, whereas ratio data can be multiplied and divided, and this is one of the notable differences between these measurement scales, which can only be added and subtracted.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, in ratio data, the difference between 5 and 6 is the same as the difference between 7 and 8, and 10 is twice as much as 5. This measurement is impossible in interval data.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Measure_Ratio_Scale\"><\/span><strong>How to Measure Ratio Scale<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Researchers can perform all statistical analyses on ratio data to identify patterns and trends for informed business decisions. For example, the ratio data of marks obtained by 100 students for an exam can be analyzed by both descriptive and inferential statistics.<\/span><\/p>\n<h3><strong>1. Descriptive Statistics<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Descriptive statistics intend to present a big chunk of data with summary charts, graphs, and tables, making it easier to understand and visualize raw data.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For the results of 100 students, you may want to analyze the overall performance of the students and the distribution or spread of the marks. This can easily be done by descriptive statistics.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Data that comes from descriptive statistics include the <\/span><b>mode, median, and mea<\/b><span style=\"font-weight: 400;\">n, along with the <\/span><b>range, variance, and standard deviation<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To explain it fully:<\/span><\/p>\n<p><b>1. Measures of central tendency<\/b><span style=\"font-weight: 400;\">: It incorporates the ways of describing the central position of a frequency distribution for sample data, which can be described by using a number of statistics, including the mode, median, and mean.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The mean is equal to the sum of all the values in the data set divided by the number of values in the data set.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The mode is the most frequent value in the data set.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The median is the middle value for a data set when arranged in order of magnitude (smallest first).<\/span><\/li>\n<\/ul>\n<p><b>2. Measures of spread<\/b><span style=\"font-weight: 400;\">: It summarizes the data by describing how spread out the values are. You can use several statistics to describe the data spread, including the range, variance, and standard deviation.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The range is the simplest measurement that denotes the difference between the values in a data set. To find the range, simply subtract the lowest value from the greatest value of the data set.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The variance is a measure of variability that indicates the degree of spread in the data set. The greater the spread, the larger the variance in relation to the mean. It is calculated by taking the average of squared deviations from the mean and is expressed as meters squared.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A standard deviation represents how dispersed the data is in relation to the mean. A low standard deviation means data is clustered around the mean, whereas a high standard deviation indicates data is more spread out.<\/span><\/li>\n<\/ul>\n<h3><strong>2. Inferential Statistics<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">While descriptive statistics are used to present the ratio data in a meaningful way, inferential statistics help study the data even further to draw conclusions and hypotheses about the same information. The main areas involved are:<\/span><\/p>\n<ol>\n<li><b> Estimating parameters<\/b><span style=\"font-weight: 400;\">: This means taking a statistic from your sample data (such as the sample mean) and using it to draw conclusions about the data sample<\/span><\/li>\n<li><b> Hypothesis tests<\/b><span style=\"font-weight: 400;\">: These tests are used to answer research questions. For example, one might be interested in knowing if a newly launched product feature is effective or if a specific product helps customers perform better in business.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">The main indexes for inferential statistics are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Binomial Theorem<\/b><span style=\"font-weight: 400;\">: For probability distribution and outcomes in binary scenarios.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Hypothesis Testing<\/b><span style=\"font-weight: 400;\">: To accept or reject a hypothesis based on data evidence.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Normal and T-Distributions<\/b><span style=\"font-weight: 400;\">: Useful in assessing data distributions and sample means.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Regression Analysis<\/b><span style=\"font-weight: 400;\">: For examining relationships between variables and making predictions. Linear regression, in particular, explores correlations between two variables.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Comparison of Means<\/b><span style=\"font-weight: 400;\">: Used in tests like T-tests or ANOVA to assess differences between groups.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Leverage_the_Power_of_Ratio_Scale_for_Your_Next_Research\"><\/span><strong>Leverage the Power of Ratio Scale for Your Next Research<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Using the right type of measurement scale could certainly help you capture meaningful data and make informed business decisions. The ratio scale helps users collect intense insights and works best with inferential and descriptive analysis techniques.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Are you ready to understand your market size, annual sales, revenue, and pricing?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">ProProfs Survey Maker can help you create the most engaging ratio scale surveys and questionnaires using ready-made <\/span><a href=\"https:\/\/www.proprofssurvey.com\/templates\/\"><span style=\"font-weight: 400;\">survey templates<\/span><\/a><span style=\"font-weight: 400;\"> and <\/span><a href=\"https:\/\/www.proprofssurvey.com\/blog\/survey-question-examples\/\"><span style=\"font-weight: 400;\">survey questions<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><a href=\"https:\/\/www.proprofs.com\/survey\/register\/?demo&amp;_gl=1*5zsd9a*_ga*ODg0NTgxNzY5LjE3MjUwMjEzODQ.*_ga_P54MCCV7GP*MTczMDk1NjEwNC4xMzMuMC4xNzMwOTU2MTA0LjAuMC4w\"><span style=\"font-weight: 400;\">Get a demo<\/span><\/a><span style=\"font-weight: 400;\"> or <\/span><a href=\"https:\/\/www.proprofs.com\/survey\/register\/?_gl=1*5zsd9a*_ga*ODg0NTgxNzY5LjE3MjUwMjEzODQ.*_ga_P54MCCV7GP*MTczMDk1NjEwNC4xMzMuMC4xNzMwOTU2MTA0LjAuMC4w\"><span style=\"font-weight: 400;\">get started free<\/span><\/a><span style=\"font-weight: 400;\"> today!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>While collecting data from various types of surveys and questionnaires, marketers often use four types of data measurement scales: Nominal, Ordinal, Interval, and Ratio Scale.
