I watched your sampling strategies and loved it. It was a huge benefit for me in research methods. This video on multiple regression is one of the best I've ever seen! You make it so easy to understand, and the demonstrations take away the anxiety quick. Keep up the great work!

Thanks Christopher, that is so gratifying. I was just looking today at all the other videos by other people and wondering if it was worth adding to them. I will carry on!

Thank you very much. A quick question. Since we’re writing the hypotheses for the F-test as: H0: β1 = β2 = ... = βk = 0, is it possible to use H0:βk=0 for the t-test (instead of H0: βj=0)? Thank you!!!

Sorry - I've looked at this question a few times and I can't work out what you are asking. Can you try wording it differently please.
