Understanding Mean, Median, and Mode

In this lesson, we will learn how to analyze data sets and calculate the mean, median, and mode.

Mean

• To calculate the mean, add all the numbers and divide by the total number of values.

Median

• The median is the middle value when the numbers are arranged in order.
• If there is an even number of values, the median is the average of the two middle numbers.

Mode
