Which data set has a median of 15? 9, 17, 13, 15, 16, 8, 12 18, 15, 11, 14, 19, 15, 6 7, 16, 14, 16, 11, 7, 17 18, 9, 19, 16, 6, 20. 13 don't answer if you don't know the answer and you

The middle number of the data set or average of the two middle numbers in even numbered sets.

Step-by-step explanation:

A median is the middle point of a data set. We order the numbers from least to greatest and find the number directly in the middle of the list. If there are an even number in the set, then we take an average of the middle two.

The data sets are not separated. However, in the sets you have order them least to greatest each. Then count in from both sides to the middle. That number is the middle.

18, 15, 11, 14, 19, 15, 6

Step-by-step explanation:

1. 7,7,11,14,16,16,17 : 14 is the median

2. 6,9,13,16,18,19,20 : 16 is the median

3. 8,9,12,13,15,16,17 : 13 is the median

it's basically the middle number of the pattern once you put in in order from least to greatest or greatest to least .
