• 6.89

• 10.1

• 7.26

• 9

The data sets show the test scores of a group for the last two tests.

Test 1: {75, 75, 85, 80, 65, 70, 65} Test 2: {95, 85, 85, 90, 90, 95, 100}

Which data set had the SMALLER standard deviation?

• Test 1 with a standard deviation of 6.9

• Test 2 with a standard deviation of 6.9

• Test 1 with a standard deviation of 5.2

• Test 2 with a standard deviation of 5.2

All of the below sets have the same mean.
Set 1-Standard Deviation=3.1
Set 2-Standard Deviation=4.9
Set 3-Standard Deviation=1.7
Set 4-Standard Deviation=3.2
