Definitions:

Mean Score

The average value obtained by dividing the sum of all values in a set by the number of values in that set; used as a measure of central tendency in statistics.

Standard Deviation

A statistical measure of the dispersion or variability within a set of numerical data, indicating how much individual data points differ from the mean.

Mode

The most frequent score.

Median

The median is a measure of central tendency that divides a data set into two equal halves, representing the middle value when the data set is ordered.
