Mean, Median, Mode & Range

Definition Mean Means Average

MeanMean – the average of a group of numbers.

Female Male

685 ÷ The mean is 14 = ÷ 2=10.4 The mean is 10

Definition Median is in the Middle

Definition MedianMedian – the middle number in a set of ordered numbers.

How to Find the Median in a Group of Numbers Step 1 – Arrange the numbers in order from least to greatest. 16, 16, 12, 5, 19 5, 12, 16, 16, 19 F M 8, 8, 1, 29, 6 1, 6, 8, 8, 29

5, 12, 16, 16, 19 1, 6, 8, 8, 29 F M The median is 16. The median is 8.

Definition Mode is the most Popular

ModeMode – the number that appears most frequently in a set of numbers.

F The value 16 appears twice. All other numbers appear just once. 16 is the MODE

M The value 8 appears twice. All other numbers appear just once. 8 is the MODE

Definition Range is the distance Between

RangeRange – the difference between the greatest and the least value in a set of numbers.

F is the RANGE or spread of this set of data

M is the RANGE or spread of this set of data
