8. In order: 4, 6, 7, 9, 10, 12 6 data items so median is mean of middle two: median = (7+9)/2 = 8.
Median of the set = arithmetic mean of 8 and 9 = 8.5
8
It is 9.
Median: 8 Mode: 8, 9 Range: 6
The median is 8.

median = 8 mean = 7 mean < median.

7 and 9 are in the middle so you add 7 plus 9 to get 16 then divide by two so 16 ÷ 2 is 8 therefore the median is 8
so to find the median you have to line the numbers up in order your median is the number in the MIDDLE so your line up would be : 2 3 4 7 9 10 10 13 so start to cross out until you find the middle number / 3 4 7 9 10 10 / / / 4 7 9 10 / / / / 7 9 / / / so you have two numbers left 7 and 9 so find the number in between . which would be 8 8 is you answer
5.5
Arrange the numbers in RANK order. This has been done. Since there are terms, we find the median by taking the two middle terms '10' & '8' and finding their means (10+8)/2 = 18/2= 9 '9' is the median term.
