Is the middle value in a set of data when the data is ordered from least to greatest

Yes, in order to find the middle value in a set of data (the median), you must order the values from smallest to largest and then it is the one in the centre of the list.

Eg. 7, 8, 3, 10, 6

Order

3, 6, 7, 8, 10

There are 5 values

5 + 1 = 6

6/2 = 3

The 3rd place in the list is the median value.

7 is the middle value.
