MEASURES OF CENTRAL TENDENCY

MEASURES OF CENTRAL TENDENCY. Measures of central tendency try to describe what we refer to as the center of the data. Here are four sets to look at A = {2,3,6,7,7,8,9} B = {2,4,7,7,8,8} C = {2,7,9} D = {2,2,2,6,8,9,9,10} Where does the center appear to be for each?.

Measures of central tendency

Measures of central tendency. The Mean (or Average). The sum of all of the numbers in a set, divided by the number in the set There are 8 students in a class. Grades on the exam were 63, 72, 84, 89, 96, 96, 99, 100 The average is (63+ 72 + 84 + 89 + 96 + 96 + 99 + 100) / 8 = 87.4.
