Statistics are an important part of data analysis and are used by many people and many businesses on a daily basis. While there are many different types of statistics, this lesson will teach you how to calculate mean, median, mode, and range.

Basketball Statistician

There are three seconds left in the game. He shoots and scores!! The Tigers win the state championship! In your new position of team statistician, a person who keeps statistics, you will travel with the basketball team and record statistics, which means you are going to analyze data.

Before you go to the team's first game, you must learn how to analyze the statistics of the mean, median, mode and range of a set of data.

Mean

When you hear the word mean think of an 'average'. To find the mean, you add all the numbers together and divide by the amount of numbers you added.

For example:

Find the average of 4, 5, and 9

4 + 5 + 9 = 18

18/3 = 6

The average of this set of data is 6.

Median

When you hear the word median think of the word 'middle'. A median is a number that is in the middle of the data. To find the median, list the numbers from least to greatest and find the number that is exactly in the middle.

For example:

Find the median of 3, 8, 5, 1, and 7

Put the numbers in order from least to greatest - 1, 3, 5, 7, 8

The number in the middle is 5, so the median is 5.

Mode

When you hear the word mode, think of the words 'most often.' The mode is the number that appears the most in a set of data.

For example:

Find the mode of 5, 6, 7, 5, 3, 2, 5

The mode of the data is 5 because there are more 5's than any other numbers.

Range

The range of the data is the difference between the largest number and the smallest number in a set of data. To find the range, subtract the smallest number in the data set from the largest number in the data set and the difference is the range.

For example:

Find the range of the data 4, 8, 6, and 5

The largest number is 8 and the smallest number is 4.

8 - 4 = 4

The range of this data is 4.

Game Time

The new season started with a bang! In the last seconds of the game, the Tigers shoot a 3-pointer and win by 6!

The scores for the whole season are as follows:

Game 1 - 84

Game 2 - 75

Game 3 - 68

Game 4 - 82

Game 5 - 93

Game 6 - 82

Game 7 - 76
