Mean, Mode, Median And Range From Discrete Data

Overview

A single number can summarize a whole data set. The mean, mode and median each pick out a typical value in a different way, while the range measures how spread out the data is. Together they are the everyday language of statistics.

In this lesson you will calculate the mean, mode, median and range from discrete data, and understand what each one tells you and when each is the most useful.

Objectives

  1. Calculate the mean, mode, median and range from discrete data, and (Extended) the modal class and estimated mean for grouped data.
