In the past week I have made a couple of new videos. The first, "How To... Create a Random Data Sample in Excel 2013" is inspired by Jack Fraenkel and Norman Wallen's 2006 book "How to Design and Evaluate Research in Education" (p237) and uses Excel's Data Analysis Toolpak.
The second video is simply a remake of an Excel 2010 video about calculating the Mean and Standard Deviation of a sample of data. The 2010 version is a surprisingly (to me) popular video with 315,159 views on my channel, so I'm hoping that an Excel 2013 version will be just as popular.
