  1. Mean, Median, Range & Mode

  2. REVIEW VIDEO:

  3. MEAN:

  4. 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

  5. MEDIAN: In the MIDDLE

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

  7. 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

  8. 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

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

  10. 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

  11. MODE: MODE OF ST TE N

  12. 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

  23. 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
