• C) t_critical = 2.845.
• D) F_critical = 5.93.
• E) F_critical = 19.44.

Definitions:

IQR

Stands for Interquartile Range, a measure of variability in statistics that describes the middle 50% of values when ordered from least to greatest.

Range

Range is a measure of the spread or dispersion within a data set, calculated as the difference between the highest and lowest values in the set.

Median

The middle value in a data set when the values are arranged in ascending or descending order, or the average of the two middle numbers if the data set has an even number of observations.

Standard Deviation

A statistical measure that quantifies the amount of variation or dispersion of a set of data points.
