Levels of measurement, also called scales of measurement, tell you how precisely variables are recorded. In scientific research, a variable is anything that can take on different values across your data set (e.g., height or test scores).There are 4 levels of measurement:...
When we talk about levels of measurement, we’re talking about how each variable is measured, and the mathematical nature of the values assigned to each variable. This, in turn, determines what type of analysis can be carried out. Let’s imagine you want to gather data relating to people’...
The definition of a ratio scale is a variable measurement scale that not only determines the order of the variables but also reveals the differences between them and provides information on the value of true zero. It is determined by making the assumptions that each variable has a zero choice,...
This chapter discusses the levels of measurement. In both interval and ratio scales, distances that are numerically equal in terms of the measurements themselves must stand for distances that are equal in terms of the variable being measured. These scales are distinguished by the fact that the ...

Levels of Measurement. 1. Levels of Independent Variables (Factors) A level infactor analysis,or a level of anindependent variable, means that the variables can be split up into separate parts. For example, let’s say you were studying the effect of alcohol on performance in a driving simula...
kind of variable do we want to express our test statistic in. Let us suppose that we are collecting the blood group of people. In this case, are variable will be the nominal level of measurement. In other cases, we can choose either the ordinal, interval or ratio level of measu...
Nominal, Ordinal, Interval & Ratio are the 4 fundamental levels of measurement scales used to capture, classify and analyze collected data.
The operational measurement of level of aspiration was accomplished by using a physical task, a ring-toss game, and an intellectual task, spelling. In the investigation, children were asked to state how many of ten rings they would like to throw onto a peg and how many of ten words they ...
