Common mistake: Neglecting to think adequately about possible consequences of Type I and Type II errors (and deciding acceptable levels of Type I and II errors based on these consequences) before conducting a study and analyzing data. Fail to reject the null hypothesis when there is a genuine effect – we have a false negative result and this is called Type II error. So in simple terms, a type I error is erroneously detecting an effect that is not present, while a type II error is the failure to detect an effect that is present. 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 of significance and the power for the test. Therefore, you should determine which error has more severe consequences for your situation before you define their risks. When hypothesis testing arrives at the wrong conclusions, two types of errors can result: Type I and Type II errors (Table 3.4). Incorrectly rejecting the null hypothesis is a Type I error, and incorrectly failing to reject a null hypothesis is a Type II error.

Type I. Ho: Drug is not effective. Ha: Drug is effective. There is insufficient evidence the drug is effective when the drug is effective.

Example 1: Two drugs are being compared for effectiveness in treating the same condition. I was checking on Type I (reject a true H$_{0}$) and Type II (fail to reject a false H$_{0}$) errors during hypothesis testing and got to to know the definitions. But I was looking for where and how do these errors occur in real time scenarios. It would be great if someone came up with an example and explained the process where these errors occur.
Table 1 presents the four possible outcomes of any hypothesis test based on (1) whether the null hypothesis was accepted or rejected and (2) whether the null hypothesis was true in reality. Now let's take this understanding of Type I errors and Type II errors and true positives and true negatives to think about what's most likely to happen in your next study.

Now let's take this understanding of Type I errors and Type II errors and true positives and true negatives to think about what's most likely to happen in your next study. I'll describe a typical situation which I think is fair and describes many of the studies that we do.

Chi-Squared hypothesis testing. 10. Analysis of 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 of significance and the power for the test. 2017-07-31 · 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. Differences between means: type I and type II errors and power.
