Definitions:

Measures of Correlation

Statistical techniques used to determine the degree to which two variables are related, indicating how changes in one variable are associated with changes in another.

Variance

A measure of the extent to which a set of scores vary on either side of their mean value. The square root of variance gives the standard deviation.

Descriptive Statistics

Descriptive statistics involve statistical techniques that summarize or describe the main features of a collection of data, including measures like mean, median, and mode.

Mean, Median, Mode

Statistical measures where mean is the average value, median is the middle value when data is ordered, and mode is the most frequently occurring value in a data set.
