- This statistics video tutorial explains how to calculate Cohen's d to determine if the size of the effect is small, medium, or large based on the differences between two sample means. This video also provides two ways to calculate the pooled standard deviation.

Nice, using Cohen's D to affect size
You explained everything in such an understandable matter! Thank you very much! You've saved my master's thesis :D
haha
What was your master's thesis about?
The Flipped Teaching Method in Higher Medical Education 😊 I made a meta analysis 😅 wanted to go out of my academic career with a bang 😂 a typical auto-goal but it paid off at the end 🙃
@@adrianamalkanova7551 I'm glad it worked out! I don't know much about the flipped teaching method, but what were your main findings?
I love you some much, you got me through college I owe my degree to you :)
Out of curiosity, what degree did you get?
Another Dlightful video!
You are Awesome Man..... U make great videos all as i need Keep POsting Love from INDIA
Thank you for beautiful explanation, there seems to be mistake at 3.22 time line 19(4)^2 = 304 and hence 3.14245
love ur videos!!
YOU'RE AMAZING
Is it valid to use the mean and standard deviation from a similar, but not exactly the same, study to estimate the sample size for a retrospective study? For example, the reference study was done in patients with diabetes, but the retrospective research will be done in patients who had a stroke.

i actually understand a mathematical equation wow
great video
what if it's a negative cohen's D? is it just the same? for the effect size???
I'm answering because this would have really helped things "click" for me earlier if someone else had answered- It doesn't matter if it's negative because that only tells us which group is less than the other. For effect size, we are just finding the difference between the groups in terms of standard deviation.
I have such a fucked up mind lmao.
How so?
Thaaaaaaank yoouuuuuuu!!
Where the 2 come from???
hehe
it would have been good to show the whole calculation and not just the answer, I cannot work out what to do 19(3)2 etc. and show the steps on the calculator. I am totally lost.
Xd hehe
