right way of using prezi-like presentation. This way we could see what is going to happen for the next, as well as keeping an eye on the calculation. I just dont like many are using prezi just for absolutely any kind of presentations. Sometimes it is not appropriate at any sense.
The 2nd part (hypothesis about hand grip) has the wrong degree of freedom. (row-1)*(column-1)=(3-1)*(2-1)=2*1=2. Not 4. This gives the p-value to be 0.3215. The Excel formula for the p-value is: =1-CHISQ.DIST(2.26938,2,TRUE) Crap - now I just continued listening to his video and he corrected it. My bad!!!
Given % of women vs men with tennis elbow being 20% vs 6%, and the null hypothesis being that they should be the same, why is the expected value = average of (20%, 6 %) ?
Hi can you help me in using nonparametric tests in my research about seasonal variations effect on human health???? like blood pressure and blood sugar level??

Thank you so much. This is very clear and helpful!
Unique Chi-sq plot, excellent job!
Really love your explanation
Please, I need to know the situations that we use Chi-square and not z-test, or vice versa. Thanks in advance.
Thanks a lot, man! great video
Could you please explain how you got the formula for Z test?
really not clear about why 0.0038 is the reason of not acceptance, in multi class tennis grip, expected value calculations??

Why don't you take an example when P
Given % of women vs men with tennis elbow being 20% vs 6%, and the null hypothesis being that they should be the same, why is the expected value = average of (20%, 6 %) ?
Ho w do you perform z test for proportions in excel on every row of a table with like 500 observations? (I need a draggable formula)
Just look up the table on the internet
HI, you haven't clearly explained how you are getting p-values, with the tables and details.
+AgamGamez There's no simple formula to produce a pvalue, by hand.
+Steve Bromann me only 10 lol.
can you explain how you got the values in pink for the hand grip table?
How did u get the value of expected for the last example?
Row total * column total / grand total
How to get that plot of hypothesis significace?
Thank you so much

i am not clear why you are using chi-square for two groups as chi-square is for more than 2 groups
thanks!!
private and business too.
Can anyone give me the link of the 2nd part of this video?
