Mean is found by evening out the
numbers

2, 5, 2, 1, 5
Mean is found by evening out the
numbers
![Page 5: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/5.jpg)
Mean is the average of a set of data. To calculate the mean, find the sum of the data and then divide by the number of data.
![Page 6: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/6.jpg)
12, 15, 11, 11, 7, 12
12 + 15 +11 + 11 + 7 + 13 = 68
68 / 6 = 12
First, find the sum of the data.
Then divide by the number of data.
The mean is 12

You can remember that “mean” means
to average because the
“mean teacher averages your
grade.”
![Page 8: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/8.jpg)
What is the median?The middle number in the set of data when written “in order” (first step we do)Given: 14, 28, 0, 1, 1
Reorder from least to greatest
0, 1, 1, 14, 28
The middle number is 1
![Page 9: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/9.jpg)
What if you have an even set of numbers?Given: 10, 0, 20, 30
Reorder from least to greatest
0, 10, 20, 30 Add the two middle numbers together.
Divide by 2. What is your median?1

What is the median of these numbers?
16, 10, 7
10
7, 10, 16
![Page 12: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/12.jpg)
Mode
Mode: the number that appears the most often.
A family has children aged 3, 4, 5, 3, 1.
3 appears twice, the other numbers only once.
3 is the mode.
![Page 13: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/13.jpg)
1, 1, 2, 2, 3, 3, 4, 4
There is NO mode
What is the mode?
![Page 14: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/14.jpg)
Yes, there are two modes.
What are they?
2 and 4
1, 2, 2, 2, 3, 3, 4, 4, 4
Can there be more than one mode?
![Page 15: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/15.jpg)
You can remember that mode means the number that occurs the most because “mode” and “most” sound alike!
![Page 16: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/16.jpg)
Range – the difference between the greatest and the least value in a set of numbers.
1, 1, 3, 7, 10, 13
Range = 12
![Page 17: Mean,Median,. Mean is found by evening out the numbers 2, 5, 2, 1, 5](https://reader035.vdocuments.net/reader035/viewer/2022062713/56649cb95503460f9498103e/html5/thumbnails/17.jpg)
First put the numbers in order from smallest to greatest.40, 30, 43, 48, 26, 47,
and 50To find the range you would take the largest number, 50, and subtract the smallest number, 26.
55 – 26 = 29
Range = 29

Did You Know…That you probably use statistics such as mean, median, mode and range almost every day without even realizing it?!?
