### Transcript of Mean , Median , Range & Mode

MEAN, MEDIAN, RANGE & MODE

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, 15THEN, 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, 18THEN, 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:

MODEO FS TT 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
