Variance - Answer - c Take each number in sample, subtract each number from
mean, square each
difference, add all, divide sum by number in
sample -1
Standard deviation - Answer - c square root of variance
, P value - Answer - c Probability of certainty / smaller p value means the more likely
the result could
not occur by
chance
