Mean, Median, and Mode


Mean = "average"

Add up all the numbers and divide by the number of items you added.

{ 4, 8, 3, 6, 8, 1, 6 }

4+8+3+6+8+1+6 = 30

36/6 = 6

Median = "middle"

Find the number in the middle

{ 4, 8, 3, 6, 8, 1, 6 }

so 1 3 4 6 6 8 8 is in order and the middle is 6

Mode = "most frequent"

Find the number that appears most frequently

{ 4, 8, 3, 6, 8, 1, 6 }

Both 6 and 8 appear twice so the mode is 6 and 8
