WebNull Hypothesis – Simple Introduction. A null hypothesis is a precise statement about a population that we try to reject with sample data. We don't usually believe our null hypothesis (or H 0) to be true. However, we need some exact statement as a starting point for statistical significance testing. WebThe alternative hypothesis is that which is accepted when the null hypothesis is rejected. It can be either one-tailed (looking at one outcome) or two-tailed (looking at both outcomes – positive and negative). If the significance level is 5%, this means that there is a 5% chance that the null hypothesis is incorrectly rejected.
