In these results, the null hypothesis states that the data follow a normal distribution. Because the p-value is 0.463, which is greater than the significance level of 0.05, the decision is to fail to reject the null hypothesis. You cannot conclude that the data do not follow a normal distribution.

WebSo, depending on the direction of the one-tailed hypothesis, its p-value is either 0.5*(two-tailed p-value) or 1-0.5*(two-tailed p-value) if the test statistic symmetrically distributed about zero. In this example, the two-tailed p-value suggests rejecting the null hypothesis of no difference. WebIn simpler terms, a p-value is used as a ‘cut-off point’ in terms of accepting or rejecting the null hypothesis. In biology, the convention is that a p-value of less than or equal to 0.05 is ‘significant’, and if our p-value is 0.05 or below (p ≤ 0.05), we reject the null hypothesis, and accept that there is a significant difference ...
