    Step-by-step explanation:

    1. Find the Mean

    (2+8+10+16) / 4=9

    2. For each number, subtract the Mean and square the result.

    (2-9) ^2=49

    (8-9) ^2=1

    (10-9) ^2=1

    (16-9) ^2=49

    3. Find the Mean of those squared differences.

    (49+1+1+49) / 4=25

    4. Take the square root of that and this is what you want.

    square root of 25 = 5
