Jul 31, · Type I errors in statistics occur when statisticians incorrectly reject the null hypothesis, or statement of no effect, when the null hypothesis is true while Type II errors occur when statisticians fail to reject the null hypothesis and the alternative hypothesis, or the statement for which the test is being conducted to provide evidence in support of, is true.

Type I error, also known as a “false positive”: the error of rejecting a null hypothesis when statistical tests are used repeatedly, for example while doing multiple. When you do a hypothesis test, two types of errors are possible: type I and type II. The risks of these two errors are inversely related and determined by the level.
