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.

What have we just learnt??

What have we just learnt??. Put the values in order then count inwards from the ends until you reach the middle. If there are two middle values, then calculate the number in the middle of them. The value that appears the most often.
