I agree. Someone once told me about the difference between learning from anyone, and a Master. Today, I have experienced what the difference is. Thank you Mr. O' Loughlin
Eugene, I'm a Mathematics teacher in NE England and your online material is fabulous. It is so helpful for students revising for their Psychology & Biology A Levels. Thank you!
Hi Keiron, Many thanks for your kind comments - I'm glad that your students find my videos useful. BTW - I find with my own students that the Chi-square test is one of the most error prone tests that they do - many forget to do the last line (O-E)2/E, and end up summing the wrong data. Warn your students of this! Dr E.
@@EugeneOLoughlin Hi Eugene, Yes, I have also noticed one or two making this error. Thankfully most seem to know what they're doing. As both the psychology & biology A-levels have a 10% maths content, your videos have proven invaluable to these students. Thanks again, Keiron
Dear Mr. O'Loughlin, I have tried to use chi-square in my forensics class. It has been used, by me, to see if there is a correlation between the medullary structure of animal hairs and nocturnality; which came up as a possible explanation for the differences in medullary structure, by chance, during a lesson. Your explanation is clear and accessible for high school students. Thank you. And, oh yes, the probability for animals that share the characteristic of cell-like structures, walking and running locomotor patterns and nocturnal activity patterns is 10.48. This is well beyond the 7.81 critical value...so further investigation is warranted. Best regards, Linda Brown Bronx, NY
Before watching the video... i was worried about the test .... now am clearly understood the concepts..... you are so brilliant....... thank you sir.....
Thanks Dr. E. for this lecture. By the way in the Philippines, it has been suggested by the academe that Chi-square (Test for Independence) must be also utilized to determine whether two classification criteria are independent of each other such that we intend to use contingency tables or in market research studies (referred to as the cross-tabs).. :)
I am repeating my 2nd year for IRM, have sat through countless lectures, asked many people and watched a million videos. 4 minutes into this video, and I have finally got itS thank you so so so much 🙏🏻🙏🏻🙏🏻

Wow, I sat through a 2 hour lecture with notes straight out of standard stats book. This was epic! Explained so you understand it, not so you have to burn it into your head. There should be something called "RUclips University". Thanks so much Sir!
