Explanatory Variables

Variables in a statistical model that are used to explain variations in the response variable.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the values deviate from the mean.

Measure Of Central Tendency

A statistical concept that provides a single value as an estimate of the center of a distribution of values, commonly calculated as the mean, median, or mode.

Outlier

Numbers in a data set that are extreme values; calculate outliers in a data set by multiplying 1.5 times the IQR; subtract this product from Q1 to compute the boundary for lower outliers and add this value to Q3 to compute the boundary for upper outliers.
