WebThis is why in the example above, where we reported a Shapiro-Wilk test with a p > 0.05, we used the words: “the Shapiro-Wilk test did not show evidence of non-normality“. So be aware of incorrect interpretations like the following: “The Shapiro-Wilk test indicates that the variable has a normal distribution“. Web20 de jul. de 2024 · Normality scores for the total number of testing frames are computed, and it will be in the range [0–1]. A threshold value is empirically chosen as 0.7, which implies that if the normality score is greater than 0.7, the test example is labeled as normal and the converse is abnormal. The null-hypothesis of this test is that the population is normally distributed. Thus, if the p value is less than the chosen alpha level, then the null hypothesis is rejected and there is evidence that the data tested are not normally distributed. On the other hand, if the p value is greater than the chosen alpha level, then the null hypothesis (that the data came from a normally distributed population) can not be rejected (e.g., for an alpha level of .05, a data set with a p value of less t… shanghainese food near me
