MEAN
Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.
In this equation, you have 8 numbers. That means you will be dividing by 8.
The first thing you need to do is add all the numbers. Add:
[tex]72+73+86+59+75+58+50+55 = \bf 528[/tex]
Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.
Divide:
[tex]528 \div 8 = \bf 66[/tex]
The mean is 66
