    Answer:

    Step-by-step explanation:

    Solve for the mean (average) of the five test scores.

    Subtract that mean from each of the five original test scores. Square each of the differences.

    Find the mean (average) of each of these differences you found in Step 2.

    Take the square root of this final mean from #3. This is the standard deviation.
