Important Formulas And Tables Statistics Pdf Loading…. To approximate one and t∗ two sided p values, compare the value of the t statistic with the critical values that match the p values given at the bottom of the table. Z e(x) = xf(x)dx = μx −∞ the variance of a pdf is defined as e[(x −μx)2] but is more easily computed as: e(x) = e(x2) − e(x)2 the standard deviation squared is equal the variance: σ2 = v (x). Descriptions of statistics formulas mean: the mean, symbolized by x bar, equals one divided by the number of samples multiplied by the sum of all data points, symbolized by x sub i.
