Study Design Part 3 - Cross Sectional Studies

[@andresmora-garcia1704]

I learned more with 15 minutes of your videos rather than 1 month in the university, thanks so much!

[@THeEthan13100]

Your OR equation is wrong, but your value is correct. A*D/B*C

[@emilienicholson7754]

Thank you. I was really confused for a while! This clears it up.

[@mizzlarabee]

I think she must have meant to say and write this ( a / b ) / ( c / d )

[@kaipings5387]

I think the formula is wrong... it should be (AxD)/(BxC)

[@nadiopewilber5251]

You right

[@cindyncole3999]

I still don’t get it lol

[@morochos92]

excellent snap shot of cross-sectional studies.. didnt yawn once ;-)

[@ghulamyaseenbozdar285]

According to this formula the result is 0.10 something ! Which is wrong.
So the right formula is A * D / B*C then the answer will be 3.71 . Thanks

[@sameheskandafi1448]

Should be A(D)/B(C) it is correct when you used numbers though

[@luvleendharni616]

Unfortunately, I am one of those few students that are struggling to comprehend the different types of studies...youre videos seem to be helping though. Please upload the other two!

[@kate12635]

thank you you have made it quite simple.

[@saramouhmmed2298]

thank you so much for the hard work you've been doing
please complete this video series ,
so excited for case control and cohort studies

[@cynthiaowusu-boakye2891]

Thank you for your great presentation, I had an issue with the OR calculation, if the formula is AB/CD the OR value should be less than 1.

[@victorparedes7756]

[@wasanalghasra]

thank you so much , but I cant find the rest of the videos for cohort and the others.

[@amandavoesten7055]

Does anyone know if you can have multiple research designs in one research? For example, a research involving a experimental and a cross-sectional design?

[@youtubesecurity4000]

How did you get 3.71 at #4 if the formula is A×B/C×D?

[@starlight8554]

My epidemiology professor did such a bad job explaining these. Thank you

[@habtamuheliso7194]

I'm media student (MA), and conducting my thesis on news coverage with sample of 51 news story. which design is relevant for this sample size? what do you recommend? case study or cross sectional design
