G*Power is a free-to use software used to calculate statistical power. The program offers the ability to calculate power for a wide variety of statistical tests including t-tests, F-tests, and chi-square-tests, among others. Additionally, the user must determine which of the many contexts this test is being used, such as a one-way ANOVA versus a multi-way ANOVA. In order to calculate power, the user must know four of five variables: either number of groups, number of observations, effect size, significance level (α), or power (1-β). G*Power has a built-in tool for determining effect size if it cannot be estimated from prior literature or is not easily calculable.

- G * Power是用于计算统计功效的免费軟體,可为各种假設檢定(包括學生t检验、F检验和卡方检验)计算功效,或是為試驗估計所需樣本數。计算功效時,使用者必須提供軟體五个变數中的四个:组数、观察数、效應值、显着性差異水平 (α)或功效 (1-β)。如果无法根据既有文献进行估算或难以计算,G * Power具有内置工具以決定效果大小。 (zh)
