The levels of ____ scale variables have no numerical, quantitative, properties. The levels are simply different categories or groups. Most independent variables in experiments are ____.
nominal
3
The variables with ___ scale labels exhibit minimal quantitative distinctions. We can rank order the levels of the variable being studied from lowest to highest.
ordinal
4
With an ____ scale variable, the intervals between the levels are equal in size. ____ scales generally have five or more quantitative levels.
interval
5
____ scale variables have both equal intervals and an absolute zero point that indicates the absence of the variable being measured.
Ratio
6
An important implication of interval and ratio scales is that the data can be summarised using the ____, or arithmetic average.
