There are three different scale types, namely Ordinal (Ordinal). Interval (Interval) and Ratio (Ratio) scales in the literature were collected under the Scale scale in the SPSS program. Let us now briefly examine these scale types.
Ratio Scale: It is used to measure variables such as monthly income, weight, length, speed. In this scale, the starting point is “0”.
Interval Scale: Quantitative measures such as temperature, success, performance
used to measure variables. The main difference of the interval scale from the ratio scale is that it does not have a starting point.
In other words, the value “0” does not mean absence in the interval scale.
For example, “0 oC” on a thermometer has a specific meaning. However, “0 Kg” in the ratio scale is an expression of absence.
In the analyzes made in the SPSS program, the difference between the two scale types
Since the said difference does not affect the result, these scales are
