Statistical Values and Calculations

This video tutorial covers basic operations in one variable statistics, including calculating statistical values such as mean, variance, and standard deviation. It guides viewers through entering data, executing calculations, and viewing results like quartiles and median. The tutorial also demonstrates how to calculate the quartile range using statistical values. The video concludes with a summary of the operations performed.
