On StatisticalBullshit.com, I recently posted a new page on the perils of small sample sizes. Some quick examples show that small samples may bias your results in unexpected ways. So be sure to read it here: https://statisticalbullshit.com/2017/08/07/small-samples-big-problems/ .
As always, if you have any statistical questions or comments, please email me at MHoward@SouthAlabama.edu!
