-To calculate the mean of a data set, add up all of the values to find a total, then divide the total number by the number of values that you have, like this:
Then, the mean of this set of data is 63.83
-To calculate the median put all of the values into order, the median is the middle value, if the number of values is even find the mean of the two values of the middle, like this:
65 72 58 62 64 62, in order:
58 62 62 64 65 72
The middle values are 62 and 64, then we take the mean of these numbers:
Then, the median of this set of data is 63
-The mode is just the most frequent value in the set of data, in this case, the value 62 appears two times, then the mode of the set of data is 62
-To calculate the range take the highest and the lowest values of the set of data, in this case, 58 and 72, then we subtract the lowest form the highest, like this:
range=72-58=14
The range of this set of values is 14
