Page 17: Data Landmarks

Correct!

The median for the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89

is 94.5 because it is halfway between the two middle values. (You will only do this when there is an even number of values. If the number of values is odd, the median is the number in the middle.)

Reorder the values: 72, 85, 89, 92, 94, 95, 95, 97, 98, 9994 + 95 = 189; 189 / 2 = 94.5

Mean

This is the value that occurs when you combine all of the values and divide them evenly.

The mean for this set of data can be found by: finding the sum of the values = 557

Dividing by the total number of values = 557 / 6 = 92.83

Page 25: Data Landmarks

Correct!

The mean for the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89

is 91.6 because when you add the values together and divide them equally (find the sum of all values and divide it by the total number of values) you get:

98 + 94 + 97 + 95 + 95 + 99 + 92 + 85 + 72 + 89 = 919

916 / 10 = 91.6
