A fire alarm provides a good analogy for the types of hypothesis testing errors. Preferably, the alarm rings when there is a fire and does not ring in the absence of a fire. However, if the alarm rings when ther

Wrongly identify a healthy person as sick and a sick person as healthy is closelyrelated to the concept of type I and type II errors of testing hypothesis. It was observed that thesensitivity of a test is equal to power of test in hypothesis testing.Devashish Sharma...

AnANOVAtest is a way to find out if survey or experiment results aresignificant. In other words, they help you to figure out if you need toreject the null hypothesisor accept thealternate hypothesis. Basically,you’re testing groups to see if there’s a difference between them.Examples of ...
T cell development in the thymus is essential for cellular immunity and depends on the organotypic thymic epithelial microenvironment. In comparison with other organs, the size and cellular composition of the thymus are unusually dynamic, as exemplified
possibility of getting astatistically significantresult when testing multiple hypotheses. It’s needed because the more tests you run, the more likely you are to get a significant result. The correction lowers the area where you canreject the null hypothesis. In other words, it makes yourp-...

In statistical hypothesis testing,the relationship oftwo types of errorsand how to reduce the probability of them are discussed,and how to choose the appropriate testing method of one-sided statistical test is also offered. 在统计假设检验中,讨论了两类错误的关系以及如何同时减少犯两类错误的概率,并...
