Glossary Definition

Definition:

A statistical error that produces a false positive result, whereby the test statistic predicts incorrectly a significant difference or correlation between groups. The likelihood of Type I errors can be reduced by using more conservative alpha level (thresholds of significance), such as 0.01 rather than 0.05. (Meyers LS et al., 2006).
