For instance, for a value of alpha = 0.05, if the p-value is greater than 0.05, then we fail to reject the null hypothesis. There are some instances in which we would need a very small p-value to reject a null hypothesis.
WebThere can be two types of variances in statistics, namely, sample variance and population variance. The symbol of variance is given by σ 2. Variance is widely used in hypothesis testing, checking the goodness of fit, and Monte Carlo sampling. To check how widely individual data points vary with respect to the mean we use variance.
