OpenStudy (jchick):

Do you know how to do this?

OpenStudy (jchick):

The mean, median, mode, and range of this data are: A. 51.9, 52, 49, 6

OpenStudy (jchick):

The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate: Just add up all the numbers, then divide by how many numbers there are.

OpenStudy (jchick):

To find the Median, place the numbers you are given in value order and find the middle number.

OpenStudy (jchick):

The mode of a set of numbers is the one that occurs most often. So, in the set {1,5,7,5,9}, the mode is 5 because there are 2 fives and only one of each of the others.
