Property Value

Cohen's d is a standardized difference between the sample mean and the hypothesized population mean in a one-sample t-test. It is calculated as the difference between the sample mean and the hypothesized mean divided by the sample standard deviation.

This value is commonly used to measure the magnitude of an effect in hypothesis testing.

When the number of observations is small, HedgesG may be more accurate.
