Mean
How do you find the mean?
Add all values together, and divide by the amount of numbers.
How do you find the median?
Order data least to greatest, the median is the middle value. If two values are in the middle, add the values together, then divide by 2.
How do you describe the mode?
Value that occurs the most.
How do you find the range?
Subtract the highest value minus the lowest value.
