... It is easy to be confused about the difference between the standard deviation (SD) and standard error of the mean (SEM). The SD quantifies scatter — how much the values vary from one another. The SEM quantifies how accurately you know the true mean of the population. The SEM gets smaller as your sam ...

For variables measured at no more than nominal scale, it is usually advisable to give all the values, either as a list, or ...
