One of the first data sets that I looked at when I was learning statistics had a number of missing observations. I was told that this was totally normal. I also noticed that the main endpoint ...

Normal distribution is a continuous probability distribution wherein values lie in a symmetrical fashion mostly situated ... If the distribution of a data set instead has a skewness less than ...

Reason 1: Extreme Values. Too many extreme values in a data set will result in a skewed distribution.The normality of data can be achieved by cleaning the data.

The final graphical tool for assessing the distribution of a set of data is the normal probability plot (i.e., normal quantile plot). Figure 2, right panel, shows the content uniformity data in a ...
