____ are used to describe the data.

Statistics

1

Statistics are used to make ____ and draw conclusions, on the basis of the sample data, about a population.

inferences

2

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.

mean

There are three basic ways of ___ the results: (1) comparing group percentages, (2) correlating scores of individuals on two variables, and (3) comparing group means.

____ ____ divide a whole circle, or pie, into slices that represent relative percentages.
