Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. The simplest measurement scale we can use to label variables is a nominal scale. In this post, we define each measurement scale and provide examples of variables that can be used with each scale. Nominal. Most statistical text books still use this hierarchy so students generally end up needing to know them. They are assigned a category. It has a different meaning and application in each of these fields. Each level of measurement has some important properties that are useful to know. Nominal. Example. Flavors of frozen yogurt _____ 2. Nominal, Ordinal, Interval & Ratio Variable + [Examples] Measurement variables, or simply variables are commonly used in different physical science fields—including mathematics, computer science, and statistics. 4. They were used quite extensively but have begun to fall out of favor. You might have heard of the sequence of terms to describe data : Nominal, Ordinal, Interval and Ratio. In scientific research, a variable is anything that can take on different values across your data set (e.g., height or test scores). Ratios Do not make sense. 2. (1 Point) nominal level ordinal level interval level ratio level 2.Determine the sampling technique used in the given statement. 3. Favorite candy bar; Weight of luggage; Year of your birth; Egg size (small, medium, large, extra large, jumbo) Each scale is represented once in the list below. Letter grades on an English essay _____ Level of Measurement Pop Quiz Identify the following as nominal level, ordinal level, interval level, or ratio level data. There are four major scales (or types) of measurement of variables: nominal, ordinal, interval and ratio. For example, only the ratio scale has meaningful zeros. Published on July 16, 2020 by Pritha Bhandari. Nominal scale: A scale used to label variables that have no quantitative values. Test your understanding of Nominal, Ordinal, Interval, and Ratio Scales. Levels of measurement, also called scales of measurement, tell you how precisely variables are recorded. Students classified by their reading ability: Above average, Below average, Normal _____ 4. Revised on October 12, 2020. Levels of measurement: Nominal, ordinal, interval, ratio. Amount of money in savings accounts_____ 3. Statement: Marital status of patients in a physician’s office. Ratio. Since an interval scale has no true zero point, it does not make sense to compute ratios of temperatures. There is no sense in which the ratio of 40 to 20 degrees Fahrenheit is the same as the ratio of 100 to 50 degrees; no interesting physical property is preserved across the two ratios. Ordinal. 1. Interval. Nominal: The nominal scale places non-numerical data into categories or classifications. These terms are used to describe types of data and by some to dictate the appropriate statistical test to use. Classify the given statement as nominal, ordinal, interval or ratio levels of measurement. In algebra, which is a common aspect of mathematics, a variable is simply referred to as an unknown value.
