What are the measures of central tendency?
The mean (or the average) is calculated by summing all the scores and dividing them by the same number of scores. The median is the middle score or value. The mode is the score that occurs the most across the set of scores. This post will help you revise the terms related to measures of central tendency and how to find them amongst a set of data in Prelim Standard Math.
