Below are sample questions representative of the exercises included on this worksheet and related ALG2.209 Standard Deviation and Variance skill assessments:

Problem 1Difficulty: Mastery

A data set has standard deviation 6. After multiplying every value by a constant k, the new standard deviation is 3. What is the value of |k| ?

A0.25

B-0.5

C0.5

D-3

Solution & Explanation:Multiplying by k scales standard deviation by |k|, so |k| = (new SD) divided by (old SD).

Problem 2Difficulty: Mastery

A data set has standard deviation 2.5. After multiplying every value by a constant k, the new standard deviation is 10. What is the value of |k| ?

A7.5

C16

Solution & Explanation:Multiplying by k scales standard deviation by |k|, so |k| = (new SD) divided by (old SD).

Problem 3Difficulty: Mastery

Which statement is always true?

AAdding the same constant to every value doubles the variance.

BStandard deviation is measured in squared units.

CIf the variance doubles, the standard deviation also doubles.

DIf the standard deviation doubles, the variance becomes 4 times as large.

Solution & Explanation:Variance is (standard deviation) squared. Doubling SD multiplies variance by 2 squared = 4.
