Which measure of central tendency is derived from the middle most value?

Answer»

The Median. To GET a median of the data, SORT your items from LOWEST to highest, and pick the middle number. If there are 2 middles (an even amount of data points), average them. Examples below.


Example 1:

Data Set: {8,3,7,4,5,0,1,3,6}

Sorted: {0,1,3,3,4,5,6,7,8}

Middle Number: 4

Median: 4


Example 2:

Data Set: {7,3,2,8,5,3,2,9,0,6}

Sorted: {0,2,2,3,3,5,6,7,8,9}

Middle Numbers: 3 and 5

Median (3 and 5 averaged): 4
