What is the Mean, Median, and Mode of a Data Set?

Mean = sum of all data points/number of data points.

Median = the middle value when the data points are ordered.

Mode = the data points with the highest frequency.

Given:

10.4, 10.3, 11.7, 11.1, 8.0, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5

Mean = 84/12 = 7

Median = (7.3+8.0)/2 = 7.65

Mode = 4.4

Range = 11.7 - 1.8 = 9.9
