I think it would be one of the mean choices though
mean - the average of a set of numbers.
To find the mean of a data set, add up all of the numbers in the set, and then divide that total by the number of numbers in the set.
median - the middle number in a set, also the number that is halfway into the set.
Arrange all numbers (even if the same number list it twice) in order from smallest to largest. mark out one at each end working way towards middle.
standard deviation - a quantity calculated to indicate the extent of deviation for a group as a whole.
IQR The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
