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.

Type I and type II errors Definition. In statistical test theory, the notion of a statistical error is an integral part of hypothesis testing. Error rate. The results obtained from negative sample (left curve) overlap with the results obtained from positive Example. Since in a real experiment, it

When you are testing hypotheses, you might encounter type 1 and type 2 errors. Identifying them and dealing with them is essential for setting up statistical testing scenarios. They also play a huge role in machine learning.
