4) Given the following set of data, what is the

value of x so that the median of the data is 10?

3, 4, 7, 9, x, 12, 14, 18

x = 11

Step-by-step explanation:

Median = The middle value of the set

There are 8 data values in the data set. You can split it up by 2 in order to get 4 and 4. There are two middle numbers that make up the median

3 4 7 9 x 12 14 18

We know that in order to find the median, we have to divide the two numbers by 2. If the median is 10, 10 by 2 equals 20. 9 plus 11 equals 20,

3 4 7 9 11 12 14 18

x = 11
