Ryan, You are most welcome.

For the Odds Ratio question, I believe the answer should be (60/40)/(200/160). Odds Ratios (a/c)/(b/d) represent the odds of exposure among cases (a/c) vs odds of exposure among controls (b/d). In this problem, being old is represented as the exposure (a,b) and the case is represented as a low score (c,d).

@ronnymervis6963

Just to add a little to this. His equation/answer was just written incorrectly. it should have been "(60/200)/(40/160)" as opposed to "(60/200)/(40)/(40+160)". Rearranging the fraction, as you did (i.e., (a/b)/(c/d) rearranged to (a/c)/(b/d)) yields the exact same answer (OR=1.2)

Thankful that you exist!!

My only regret is that I didn't find these videos earlier as my Step 3 is 1 week from today but even so they were more helpful than a whole 2 weeks of studying Biostats so thank you so much Dr Neil and God Bless you!

In last question about the Odss Ratio, the answer should be (60/200)/ (40/160), why is it option C? And in the question about the RR about the prostate cancer The formula you wrote is (a/a+b)/ (c/c+d) 15:43 and because "first on top" it goes backwards, (c/c+d)/(a/a+b), but still, the process you followed was (b/b+d)/ (a/a+c)... im confused

Sir in the Question explained from 21:08 to 22:40 they have grouped the students on the basis of independent variables(age) so this should be a Cohort study not a case control and hence the next Question should ask about Relative risk not odds ratio bye the way you are great sir thank you

Thank you again.

Thank you for your help Dr Neil! Just one question. On 22:10 you said it is a case control study. I think it is a retrospective cohort since we can look at low USMLE scores as a disease. So if we have two groups, one with a risk factor for low score (being older) and one without the risk (being younger) and we look retrospectively to see if they had low scores ('a disease') then I would consider it a cohort study. It is similar to observing if smokers and non-smokers developed COPD or SCLC. If it was a case control, we would have a group with low scores (a disease) and a group without low scores (no disease) and then we would look if they were exposed to a risk factor such as an old age. Please correct me if I'm wrong.

That is what the table indicates, a group of low score vs a group with no low score and they're studying how many people were older than 50 in both groups and what are the odds of you getting a low score if you're older then 50. Note the text in the question gives incomplete information, the table explained it better.
