Videos

• I plan to make a number of YouTube videos on individual concepts in the book.  These will all be on the YouTube Channel "Statistics from A to Z-- Confusing Concepts Clarified". You can always find it by a YouTube search on the text in quotes above. Or use this URL: bit.ly/2dD5H5f  

Please subscribe to the channel to be notified of new videos. I plan to upload one about every two weeks. 
On this page, below, you can always find which ones are available now and which are planned next.
