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.
8
median = 8 mean = 7 mean < median.

Median: 8 Mode: 8, 9 Range: 6
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
5.5
It is 9.
Mean: 5.5 Median: 7 Mode: 9, 0, 8
