**Mean, Median, Mode, and Range**

Learn about mean, median, mode, and range of a data set

Example:

Find the mean, median, mode, and range of each dataset.

**Statistics: The Average**

Introduction to descriptive statistics and central tendency.

Ways to measure the average of a set: median, mean, mode

**Mean, Median, and Mode**

Learn about Mean, Median, and Mode

Mean, median and mode are measures of central tendency. Mean: add together and divide by how many there are.

Median: the middle number when the data is listed in order from smallest to largest. If there are 2 middle number, add them and divide by 2.

Mode: the most frequent number.

Example:

Find the mean, median and mode of this set of data.

35,8,12,50,55,22,34,22,34**Mean, Median and Mode**

This lesson shows how to calculate Mean, Median and Mode and some tricks to help you remember the differences of these methods of finding the Center.

The mean is the average.

To calculate the mean, you add add the values and divide by the number of values.

Example:

1. If you had 20 pencils in one box and 30 pencils in a second box, what is the average number of pencils in your boxes?

2. Your grades out of 20 are all listed below. What is your average grade out of 20?

15, 16, 20, 12, 18, 20, 17

The median is the center.

List the numbers in order and pick the center one. If there are an even number of numbers find the mean of the two middle numbers.

The mode is the number that shows up the most. There can be more than one mode. If the values all appear the same number of times, there is no mode.
