- mean/median/mode/range
- MO =MOST COMMON
- MED = MIDDLE VALUE
- MEAN = AVERAGE BUT IT'S MEAN AS YOU HAVE TO WORK IT OUT!
- RANGE = HOW FAR FROM SMALLEST TO BIGGEST
- GOLDEN RULE FOR ALL - ALWAYS REARRANGE IN ASCENDING ORDER
- FOR EG: FIND MEAN MEDIAN MODE AND RANGE OF THESE NUMBERS: - 6,-1,5,-5,0,2,8,8,-7,9,6,8 (12)
- 1. FIRST REARRANGE THEM - -7,-5,-1,+0+2+5+6+6+8+8+8+9 (12).
- 2. MEAN = TOTAL AND DIVIDE THE TOTAL BY NUMBER OF NUMBERS. I.E. 39/12=3.25
- MEDIAN= FIND THE MIDDLE VALUE (ONLY WHEN ARRANGED IN ORDER OF SIZE)
- MODE= MOST COMMON VALUE =8
- Untitled
- MODE= MOST COMMON VALUE =8
- MEDIAN= FIND THE MIDDLE VALUE (ONLY WHEN ARRANGED IN ORDER OF SIZE)
- 2. MEAN = TOTAL AND DIVIDE THE TOTAL BY NUMBER OF NUMBERS. I.E. 39/12=3.25
- 1. FIRST REARRANGE THEM - -7,-5,-1,+0+2+5+6+6+8+8+8+9 (12).
