answer

Validity --$400

An ______ variable is a variable that is not being directly studied, but has the potential of changing along with the independent variable.

answer

Validity -$500

answer

Frequency Distributions --$500

A mathematical procedure for estimating a value that is located between two known values.

answer

Descriptive Stats--$100

A statistical measure that determines a single value that accurately describes the typical score of a distribution.

answer

Descriptive Stats--$200

This measure of central tendency is the score at the 50th percentile.

answer

Descriptive Stats --$300

This measure of variability measures the average distance between scores and the mean.

answer

Descriptive Stats --$400

This measures the average of the squared distances from the mean.

answer

Descriptive Stats --$500

In order to calculate this, take the square root of the population variance.
