The Ordinal scale includes statistical data type where variables are in order or rank but without a degree of difference between categories. Nominal, ordinal, interval, ratio. The Interval scale quantifies the difference between two variables whereas the other two scales are solely capable of associating qualitative values with variables. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. Different types of data are used in research, analysis, statistical analysis, data visualization, and data science. However, parametric tests are more powerful, so well focus on those. For example: If you collected data on hair color, when entering your data into a spreadsheet, you might use the number 1 to represent blonde hair, the number 2 to represent gray hair, and so on.

Our graduates come from all walks of life. For instance, jobs with different levels of income can be ordered as a way to represent the magnitude difference. Unlike the ordinal scale, however, the interval scale has a known and equal distance between each value on the scale (imagine the points on a thermometer). Nominal Data is used to label variables without any order or quantitative value. An interval variable has a defined interval between values but lacks a zero point. The scale cannot generate a precise comparison between the two categories. The best. Discrete data is a sort of numerical data that consists of full, concrete numbers that have particular and fixed data values that are determined by counting.
