First calculate the mean median mode and range for the follo
First, calculate the mean, median, mode and range for the following data sets.
Set 1: 1, 2, 4, 6, 9
 Set 2: 10, 20, 40, 60, 90
 Set 3: 1, 2, 4, 6, 90
Then: Pretend that you do not have the data sets, but only the statistics that you just calculated.
What would the statistics tell you about each data set?
In each case, tell whether you think the standard deviation will be large or small compared to the mean
Solution
Set 1: 1, 2, 4, 6, 9
Mean = 4.4
median = 4
 Set 2: 10, 20, 40, 60, 90
Mean = 44
Median = 40
Set 3: 1, 2, 4, 6, 90
Mean = 20.6
Median = 4
In first two, sd is not too much large compared to last case.
