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
