Question

If the variance of a set of scores is 100, the standard deviation is _______ (in integer).

Hint:

Always remember: Variance = (Standard Deviation)\(^2\). To find SD, just take the square root of variance.

Answer 1

Correct Answer: 10

Step 1: Recall the relationship.
Standard deviation (SD) is the square root of variance.

Step 2: Apply formula.
\[ \text{Variance} = 100 \] \[ \text{SD} = \sqrt{100} = 10 \] Final Answer: The standard deviation is 10.
