When one accepts a null hypothesis which is actually false is called as type II error, beta risk or false negative. The error also rejects the alternative hypothesis. A null hypothesis occurs when there is no association or relationship among the group of data. Enter the null hypothesis, alternate hypothesis, sample size and standard deviation in the beta error - statistics calculator to calculate type II error.
Engineers calculate type II error and then accordingly choose the sample size. Find the type two error easily using the beta error - statistics calculator.
