Answer:

Order the set of values

9, 10, 11, 12, 14, 20

<h2>Median:</h2>

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

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

= 12.666...

= 12.7 to the nearest tenth.
