Northcentral uses G*Power, which is required in this Activity. You will use G*Power’s “a priori power analysis” function to calculate a sample size. If it yields an unrealistically large size sample, you will rethink your design and assumptions and, perhaps, use G*Power’s. The formula for the sample size can be written mathematically as follows: When you want to identify the sample size for a larger population, one can use the following formula. S = (Z2 * P * Q) / E2. When you want to identify the sample size for a smaller population, the above formula can be modified like below. Ssmall = S / (1 + ( (S – 1) / N)).

As the results show, the sample size required per group is 118 and the total sample size required is 236 (Fig. 1). The statistical significance level, alpha, is typically 5% (0.05) and adequate power for a trial is widely accepted as 0.8 (80%). The higher the power (power = 1 – beta) for a trial, the larger the sample size that is required. GPower 3.1.97 was available to download from the developer’s website when we last checked.

Intuitively, type I errors occur when a statistically significant difference is observed, despite there being no difference in reality, and type II errors occur when a statistically significant difference is not observed, even when there is truly a difference (Table 1). In Table 1, the significance level (α) represents the maximum allowable limit of type I error, and the power represents the minimum allowable limit of accepting the alternative hypothesis when the alternative hypothesis is true.
