The McNemar test

[@elenapopova4569]

Thank you very much about this video! It is very clear and informative! I wish you all the best! :)))

Is there a proof of the formula of the McNemar test ? TKS🙏

May I ask for the explanation of area the right-hand side of 10 in a chi-square distribution with one degree of freedom is equal to 0.0016 how did you get it.

[@tilestats]

I used a software (R).
1-pchisq(10,1)
Have a look at this video that explains how:

Awesome explaination! It helped a lot, thank you :D

According to the results would the significance mean that drug B is less effective than drug A bc more people respond to it ?

[@tilestats]

I would say that drug B is more effective to use in the population because more people respond to it.

Hi! How did you get the 0.0016? I can't seem to get it.

[@tilestats]

Did you use a chi-square distribution with one degree of freedom?
Here is a more exact value 0.001565402 if my rounding has confused you.

@@tilestats Kinda new to chi-square distribution graph im looking for it in the chi square distribution table

[@tilestats]

You need a software, such as R, to compute the p-value. If you use a table, the critical value is 3.84 with 1 degree of freedom and a significance level of 0.05. Since 10 is bigger than 3.84, you reject the null hypothesis.

what would be the appropriate test to compare (pre-post comparison) the 2 categorical (3 by 4) dependent variables

[@tilestats]

Check if the Cochran's Q test fit your problem. It is the corresponding test when you have more than 2 treatments.
