The Z Score Test For Two Population Proportions Is Used When You Want To Know Whether Two Populations Or Groups (E.g., Males And Females;
The sample means of the two groups being compared. The z score, which measures the number of standard deviations a data point is from the mean. The sample standard deviations are optional, and we only use them to validate the population standard deviations. Web this is a simple z score calculator that calculates the value of z (and associated p value) for two population proportions.
Z = X ¯ − X ¯ Σ 1 2 N 1 + Σ 2 2 N 2 = 1.65 − 1.43 0.0676 2 30 + 0.0484 2 35 = 3.64837.
