Range
This is the difference between the highest and lowest values in a data set.
96, 94, 98, 90, 94, 85
The range for this set of data is 8 because the maximum (98) minus the minimum (90) = 8
Try One!
Find the range for the following data set:
98, 94, 97, 95, 95, 99, 92, 85, 72, 89

18
Correct!
The range for the data set :
98, 94, 97, 95, 95, 99, 92, 85, 72, 89
is 27 because 99 (max) – 72 (min) = 27

Median
This is the middle value in a set of data.
The median for this set of data is 94 because it is the middle value.
85, 90, 94, 94, 96, 98
Try One!
Don’t forget to put the data in
order from least to greatest first!
Find the median for the following data set:
98, 94, 97, 95, 95, 99, 92, 85, 72, 89
94
97
94.5
95
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
85, 90, 94, 94, 96, 98

Find the mean for the following data set:
98, 94, 97, 95, 95, 99, 92, 85, 72, 89
95
91.6
99
90
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
