I've watched thousands of hours of videos on various learning topics, and by far the way you present and articulate the material is among the best. Clearly you know your subject and you have a passion for imparting that knowledge upon others. Thank you!!!
Exceedingly helpful! It is almost impossible to be too explicit when trying to explain stats to a bonehead like me...altho I seem to have run across a lot of people LIKE me when discussing stats. Well done! You get a gold star AND a thumbs up!
Your visuals are EXTREMELY helpful & clarifying. Also, super thanks for having a slightly slower rate of speech than many statisticians, also actual examples worked into every single level or type of test. VERY helpful.
Man, you're my favorite. Thanks! Finally someone answered my question. Cause I have to do a biostatistics report and I had no clue which test to use. As I asked my professor, he got me more confused 😩.
Hello doctor. If I want to see the change in sales before and after the covid19. Then should I use paired sample t test or any other test. Can you please suggest.
It was the best explanation i'v ever seen for this subject. As an ESL speaker it was easily comprehensible for me. Thanks a lot for your fantastic work!!
sir, you are a lifesaver.i ve been struggling with the basic principle of how scientifically to choose stat. methods for medical research for a while now.thanx a lot
Excellent presentation. Very helpful. Just want to point out that pain scale 1 to 10 is ordinal data, therefore, it's not quantitative, and it needs to be treated as categorical data. You can use the median or mode as a measure with it. Thank You.
You are absolutely correct, and I should have said that in the video. In health care (and in a lot of other fields) people use Likert data all the time as if it were interval data. But it isn't, and I'm sure statisticians pull their hair out over it.
Treating Likert data as interval data isn't always wrong and there's no consensus as to what's right and wrong. From a strictly theoretical point of view you probably should never treat Likert scale data as interval data but if you strictly followed the assumptions for every statistical test how often could use them? Have a look at this article "Likert scales, levels of measurement and the “laws” of statistics" (link.springer.com/article/10.1007/s10459-010-9222-y) and read "Can Likert Scale Data ever be Continuous?" at www.theanalysisfactor.com/can-likert-scale-data-ever-be-continuous/.
thankyou very much for this video! i have to compare alcohol consumption on few memory test variables ( about 5 variables) which test would i use? can i use indipendent sample t test 5 times or 1 way ANOVA ? thankyou in advance
Its a beautiful explanation and summarisation, would you please go into other statistical tests used in health and medical research include ANCOVA, Mann-whitney U test and Chi-squared?
Thank you so much for this, of all the thousands of videos I have watched on this dull subject, this by far is the best. And you are better than my uni lecturers my friend.
I am really confused, may you help please, I am looking for a complication associated with one disease. my problem is how to calculate sample size by which test? the concept is that: how many of the sample subjects will be having that complication? Thank you

if i'm analysing students' CGPA, is it considered as quantitative or categorical data?
Sorry I missed this months ago. Grade point averages would be considered quantitative. (Interval if you want a more specific level of data.)
Thanks dear
Very well explained. Crystal clear, Thank you.
