MODE → 3 STAT → 1 SD → 5 S-VAR

(2) x̄ mean

(4) xσn-1 standard deviation

(3) xσn population

1: RSD

RSD = s / x̄ x 100

1: Confidence Interval

t = t crit (with Tcrit table)

s = standard deviation

N = # samples

1: Confidence Level, Significance Level

1: Q, Grubbs, t-test, degrees of freedom

1: Q, G, t-test VALUE = meaning

If calculated Q/G/t is MORE THAN > critical value = REJECT or WITH SIGNIFICANCE

1: Two-sample T-test, Degrees of freedom

degrees of freedom (2 sets) = N_set1 + N_set2 - 2

1: F-test
