Question

what are mean median and mode its been a while since i worked with them so i cant really remember

Answer 1

The mean is the average of the numbers. To find it, add all the numbers together, then divide by the total amount of numbers (for example: 10 + 15, 25, 20/2 = 12.5, 12.5 is the average of 10 and 10)

The median is the middle value of the numbers, for instant, here's a list:
1, 2, 3, 4, 5. The median number would be 3, being the middle number (Note: Medians only work if the list is in order!)

The mode is the number that appears the most in a list of numbers. For example:
1, 2, 3, 3, 4, 5, 5, 5. The number five would be the mode, because it appears the most, more than the rest.

Answer 2

do know this too lower quartile, upper quartile, and interquartile range.

Answer 3

Just noticed I messed up on the mean example. Here's a correct version:

10 + 15
25
25 / 2
12.5
12.5 is the mean of 10 and 15.
