Neyman and Egon Pearson s mathematical foundations of hypothesis testing, which is one of the finest methodologies of reaching conclusions on population parameter. Following Wald and Ferguson s approach, the book presents Neyman-Pearson theory under broader premises of decision theory resulting into ...
Statistical tests are used in hypothesis testing. They can be used to: determine whether a predictor variable has a statistically significant relationship with an outcome variable. estimate the difference between two or more groups. Statistical tests assume a null hypothesis of no relationship or no ...
The significance level, often denoted byα, is a critical parameter in hypothesis testing that determines the threshold for rejecting the null hypothesis.Commonly used significance levels include 0.05 (5%) and 0.01 (1%),If the calculated probability (p-value) is less than or equal to the signifi...

The Bayesian approach to hypothesis testing is to base rejection of the hypothesis on the posterior probability.[3][4]Other approaches to reaching a decision based on data are available via decision theory and optimal decisions. Thecritical regionof a hypothesis test is the set of all outcomes ...
In other words, hypothesis testing is a procedure which enables researcher to decide whether to accept or reject hypothesis. There are many concepts like Type-I and Type-II errors, one-tailed and two-tailed tests, significance test, important parametric tests like Z-test, t-test, F-test and...
The Z-test is a statistical hypothesis test that establishes where the test statistic we are measuring, like the mean, is part of the normal distribution.
