Introduction Introduction # Mean, Median, Mode, and Range

INTRO
You know how the plot summary, genre, and runtime all tell us different things about a movie? Similarly, the mean, median, mode, and range are used to tell us different things about a set of numbers.  #### Genre: animated musical

Plot Summary: Aspiring musician Miguel, confronted with his family's ban on music, finds himself in the Land of the Dead looking for his great-great-grandfather, a legendary singer, and his true family history.

KEY STEPS

## How to Find the Mean, Median, Mode, and Range

Which one are you trying to find?
The mean is the average of a group of numbers.
Finding the mean is like summarizing the meaning of a movie, which takes every part of the movie into account.

Finding the Mean

## Finding the Mean

You know how a plot summary summarizes the meaning of a movie, covering each part of the movie? Plot Summary: Aspiring musician Miguel, confronted with his family's ban on music, finds himself in the Land of the Dead looking for his great-great-grandfather, a legendary singer, and his true family history.
The mean summarizes a set of numbers, where each number is part of the summary.
To find the mean, we add up all the numbers and then divide by the amount of numbers. This is also called the average.
Let’s try this out with a couple example problems where we calculate the mean!

Question 1 of 12: The mean is the average of a group of numbers. Finding the mean is like...

LESSON
Finding the Median

## Finding the Median

The median is the middle number in a set of numbers when they are in order. It's like skipping straight to the middle or halfway point of a movie. #### Halfway point: 1 hour

We can calculate the median by first ordering the numbers from least to greatest.
If there are an odd number of numbers, then the median is the number that appears in the middle.
There should be an equal amount of numbers before and after it.
If there are an even number of numbers, then the median is average of the two numbers in the middle.
Let’s try this out with a couple example problems where we calculate the median!

LESSON
Finding the Mode

## Finding the Mode

The mode is the number that shows up the most number of times. Finding the mode is like figuring out the genre of a movie - it's what's happening the most often, whether it's action, comedy, horror, or animated musical scenes. #### Genre: animated musical    We can calculate the mode by counting the number of times each number shows up. The mode is the number that shows up the most.
If there are multiple numbers that appear the most number of times, then it is possible to have multiple modes!
Let’s try this out with a couple example problems where we calculate the mode!

LESSON
Finding the Range

## Finding the Range

The range is the difference between the smallest and largest numbers in group of numbers. Finding the range is like calculating the run time from beginning to end of a movie. #### Full Runtime: 2 hours

We can calculate the range by first ordering the numbers from least to greatest, then subtracting the smallest number from the largest number.
Let’s try this out with a couple example problems where we calculate the range!
