Answer:
This is a stem leaf data, in which the stem generally stands for the "tens" place value while the leaf stands for the "ones" place value.
Expand the data, and find the median by finding the middle number:
10, 13, 16, 20, 21, 23, 27, 27, 28, 29, 30, 32, 33, 33, 33, 33, 38, 39, 46, 46, 46, 48
There are 22 numbers in all. To find the Median when there is a even amount of numbers, Find the two middle numbers, and find the mean of the two numbers:
(32 + 30)/2 = (62)/2 = 31
31 is your answer.
