The more stringent the alpha level is, the easier it is to detect an effect of the independent variable on the dependent variable.

The more stringent the alpha level is (i.e. the smaller the alpha level), the harder it becomes to detect an effect of the independent variable on the dependent variable, since it increases the likelihood of making a Type II error (false negative). Conversely, a larger alpha level makes it easier to detect an effect, but increases the likelihood of making a Type I error (false positive).

The More Stringent the Alpha Level Is, the Easier It
