The Kolmogorov–Smirnov test can be modified to serve as agoodness of fittest. In the special case of testing fornormalityof the distribution, samples are standardized and compared with a standard normal distribution. This is equivalent to setting the mean and variance of the reference distribution ...

there's the one sample Kolmogorov-Smirnov test for testing if a variable follows a given distribution in a population. This “given distribution” is usually -not always- the normal distribution, hence “Kolmogorov-Smirnov normality test”. there's also the (much less common) independent ...
QQ plot draws the correlation between a given data and the normal distribution. ggqqplot(mice, x = "weight") All the points fall approximately along the (45-degree) reference line, for each group. So we can assume normality of the data. Note that, if your sample size is greater than ...
