Definition of LEVEL OF SIGNIFICANCE. : the probability of rejecting the null hypothesis in a statistical test when it is true âcalled also significance level.
The significance level (alpha) is the probability of type I error. The power of a test is one minus the probability of type II error (beta). Power should be maximised when selecting statistical methods. If you want to estimate sample sizes then you must understand all of the terms mentioned here.f your P value is less than the chosen significance level then you reject the null hypothesis i.e. accept that your sample gives reasonable evidence to support the alternative hypothesis.
