how to find mean median and mode
Find the median of a data set with an even number of data points. Arrange the data points in ascending order of value. The median will be the sum of the two middle data points divided by 2. For example, the median of the data set {1, 2, 2, 3, 4, 5} is (2 + 3)/2 = 2.5. Calculate the mode of a data set. The mode is defined as the value in the data set that occurs most often. If more than one value occurs an equal number of times, all of these values are modes for the data set. For example, 2 and 3 are both modes for the data set (1, 2, 2, 3, 3, 4).
