of 30, 20, 15, 19, 16 100 ? 5 = 20 30 20 15 19 16 100
2. Average - Mean of values in #1 20 - 20 = 0 3. Value of S(X-8)2 on values
in #1 Dont know. It would seem that X-8 = 20 - 8. If that were the case, then 20 -
8 = 12, and 122 = 144, which is not an option unless theres an error on the list. Another approach setting x = individual scores and then summing
squares (below) also does not produce an option on the list. Is the list correct? X X - 8 (X - 8)2 30 22 484 20 12 144 15
7 49 19 11 121 16 8 64 100 60 862 4. Standard deviation of values in #1 The "standard deviation
is equal to the square root of the variance" (Saliu, n.d.). Variance (from #5 below) is 35.5. v35.5 = 9.958 = 9.56
5. Variance of values in #1 "A data series like 1, 2, 3, 6 has a mean equal to (1+2+3+6)/4=3. The differences
from the mean are: -2, -1, 0, +3. The variance is: {(-2)^2 + (-1)^2 + 0 + (3^2)}/4=14/4=3.5" (Saliu, n.d.). Thus: Difference Difference from Mean Squared 30
