Each of 6 students reported the number of movies they saw in the past year. This is what they reported: 14, 10, 20, 9, 12, 11 Find the median and mean number of movies that the students saw. If necessary, round your answers to the nearest tenth.

Order the set of values

9, 10, 11, 12, 14, 20

Median:

Middle Value

n = number of values

if n is odd, the median is at position n/2

if n is even, the median is between position n/2 and n/2 + 1

n = 6

6 is even, so the median is between position 6/2 and 6/2 + 1

the median is between 11 and 12

(11 + 12) / 2

23/2

11.5

Mean

9 + 10 + 11 + 12 + 14 + 20 = 76/6

= 12.666 ...

= 12.7 to the nearest tenth.
