WebbTwenty-six rice hybrids were evaluated at three locations. Data were normally distributed after running the Shapiro–Wilk test. Plant height and effective tillers/hills showed leptokurtic distribution, indicating these traits were controlled by fewer genes, whereas the rest of the attributes had platykurtic distribution, indicating these traits were controlled … WebbThe Shapiro-Wilk’s test tends to say things are not normal with very small deviations from large datasets. If you violate the assumption of normality, you can try transformating one …

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 th…
WebbThe Shapiro-Wilk W test can be used to check normality assumption. In this case, we set null hypothesis that residual is normally distributed. If the p-value is greater than .05, it … WebbThe Shapiro-Wilk test still indicates that the residuals are not normally distributed. We stated early that small departures from normality are okay. From the QQ plot, the …
WebbThe Shapiro-Wilk test examines if a variable is normally distributed in some population. Like so, the Shapiro-Wilk serves the exact same purpose as the Kolmogorov-Smirnov test. Some statisticians claim the latter is worse due to …
