MEAN , MEDIAN , RANGE & MODE

REVIEW VIDEO:

MEAN :

How to get the MEAN : ADD (+) the numbers THEN DIVIDE (÷) by how many numbers there are. Example: Find the MEAN of 5, 7, 10, 12, & 9 5 + 7 + 10 + 12 + 9 = 43 ÷ 5 = 8. 6 The MEAN is 8. 6

MEDIAN : In the MIDDLE

How to get the MEDIAN : FIRST, put the numbers in order from smallest to biggest. THEN, find the number in the middle.

EXAMPLE: What is the MEDIAN of these numbers: 3, 10, 7, 15, 2 FIRST, put in order: 2, 3, 7, 10, 15 THEN, find the one in the middle 2, 3, 7, 10, 15 The MEDIAN is 7

EXAMPLE #2: What is the MEDIAN of these numbers: 3, 10, 7, 15, 2, 18 FIRST, put in order: 2, 3, 7, 10, 15, 18 THEN, find the one in the middle 2, 3, 7, 10, 15, 18 The MEDIAN is 8. 5

RANGE : The distance from the smallest number to the biggest number.

How to find the RANGE : Take the biggest number and subtract the smallest number. Example: Find the RANGE of 6, 2, 10, 15, 33, 7 33 – 2 = 31 The RANGE is 31

MODE : MODE OF S T T E N

How to find the MODE: Just look at all the numbers and find the one you see the MOST OFTEN. EXAMPLE: What is the MODE of 3, 5, 7, 3, 5, 8, 3 The MODE is 3

SUPPORT SHEET: Mean = Add (+) all the numbers then divide (÷) by how many numbers there are Median = Put numbers in order, then find the one in the middle. Range = Biggest number minus (-) the smallest number Mode = The number that you see MOST OFTEN
