Bullshit Outliers

New post on StatisticalBullshit.com!  This post discusses how outliers can skew your results…and how sometimes removing outliers can also skew your results!  To read more about Statistical Bullshit, use the following link: https://statisticalbullshit.com/2017/10/09/bullshit-outliers/ .

Identifying Multiple Modes in Excel

Very early in my intro-level statistics courses, I always cover the topics of mean, median, and mode. For any dataset, there can only be a single mean and/or median value, but there can be multiple modes. For some strange reason, the =mode() command in Excel will only provide the first mode that appears in a dataset, even when multiple modes exist! For this reason, I made a guide on how to use the =mode.mult() command. Never again should you incorrectly identify the number of modes in a dataset!
