Measures of central tendency
The measures of central tendency are the mean, median and mode of a set of data. Find some lessons and calculator below. For a more comprehensive coverage of statistics, check the statistics made easy site.
Mean: The mean is the sum of the values in the set divided by the number of items in the set. There is basically no difference between the mean, the arithmetic mean, and the average. In statistics, the term 'mean' is used instead of 'average'
For example, what is the mean for 2, 4, and 6?
(2 + 4 + 6)/3 = 12/3
(2 + 4 + 6)/3 = 4
Mode: The mode of a set of data is the value or values that occur more often.
For example, the mode of 6, 5, 2, 3, 5, 1, 8 is 5 because 5 appears more often than the other values.
Median: The median of an ordered set of data is the value in the middle.
For example, the median of 4, 6, 8, 10, 12 is 8 since 8 is the value in the middle.
