What is mean, median, mode, and range.

Mean is the same as the average

median is the middle number

mode is the number that is used most often

range is the highest number minus the lowest number

example:

2,3,3,5,7

u find the mean by adding up all the numbers, then dividing by how many numbers there are. (2 + 3 + 3 + 5 + 7) / 5 = 20/5 = 4 (the mean)

the median would be the middle number, and that would be 3

the mode would be the number that appears the most ... that would be 3 because it appears twice.

the range is the highest - lowest : 7 - 2 = 5 (the range) ... bur dont get this confused by the interquartile range ... it is not the same as the range.
