Standard Deviation Practice

Standard deviation for the data set {5, 10, 7, 12, 0, 20, 15, 22, 8, 2}

What is the standard deviation for the data given: {12, 13, 29, 18, 61, 35, 21}?

Which data set had the SMALLER standard deviation? Test 1: {75, 75, 85, 80, 65, 70, 65} Test 2: {95, 85, 85, 90, 90, 95, 100}

Which data set has the largest standard deviation?
Set 1: {10, 19, 38, 50, 51}
Set 2: {5, 21, 26, 39, 51}
Set 3: {9, 38, 50, 50, 51}
Set 4: {5, 28, 28, 28, 51}

What does this symbol represent? Options: Standard Deviation, Variance, Mean Absolute Deviation, Sigma

Which set of data probably has the points closest to the 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

If the standard deviation of a data set is 4, what is the variance?

Standard deviation of sampling distribution for GPAs 2.5, 2.3, 1.7, 1.4, 1.1 (sample size 3)?

Variance for the data: 5, 10, 7, 12, 0, 20, 15, 22, 8, 2

What is the variance of the sample data set?
