Really helpful clip to understand the relationship between prevalence and PPV! Thank you!

[@elanuralper]

I cannot believe that I very easily could understand it all clearly by watching your video only 1 time , I cannot thank you enough😊

[@kp74952]

So much better than the explanations I got in class. Thank you.

[@justinahkavata2322]

A very informative clip, the interpretations are well captired.

[@elmoreglidingclub3030]

Great, GREAT video. Clear and concise explanation. (And it reveals “bureaucratic medicine” and all its dangers. I know...I’m a pilot.)

[@Alesyniana]

Wow I really appreciated the story in the end demonstrating how these numbers are used. I think I know what to look for now when studying biostat! Thank you!

[@Nadylisa]

This was really well explained. Thank you, sir.

[@tosinadeola]

Thanks. You just saved me the stress. God bless you

[@fritzfratz4020]

Thank you so much! My professor explained the PPV as confusing as possible. I tried to understand how to calculate for about an hour. After watching your video it's clear to me and it's so easy :)

[@symbioticparasite6268]

Now calculate the covid test..... You will be shocked😂😂

[@bayesianadventures6246]

Nice presentation - it's especially useful to use simple Bayesian networks to do some of the heavy lifting in calculating these figures.

[@saludalalcancedetumano9582]

Great explanation!!! Thank you

[@kinewish4017]

Very helpful video! Thank you :)

[@Footestomper]

Nice . . . I just shared this with my Statistics class!

[@darlenegnilo-dimaculangan6177]

crammed this 3 hours before an exam. Thank you. Will definitely get back to it from time to time.

thank you

[@Duol.NguotGatdoar]

I feel just like it's amazing i know how to calculate it while I don't before..

[@hekmatollahkhoubfekr2575]

Correlation between prevalence and positive predictive value

[@AymanAOT22]

How we can calculate the prevalence P(D) if we didn’t get it?

[@MarkProffitt]

Is the CV19 prevalence 3%? That would mean if the test is 90% sensitive & 90% selective the accuracy is 21.8% or other words 79.2% false positives. The asymptomatic people simply don't have it and very few of the supposed infected had it either, they likely had something else.

[@goncalodvd]

Bingo !! But no one seems to care ...

[@fatmam9662]

can someone help me please how can i caculate the prevalence of the desease ?

[@j.m.a7260]

yo whhere you get the 240

[@ryujenshogun]

for PPV why are you not putting the TP (true positive value in the denominator) its supposed to be PPV = TP/TP+FPx100 or a/a+b x 100 i would just like to clarify

[@joshuamathew1534]

He's summing it up beforehand(e.g for first one he adds the 180 and 60 before to get 260 as the denominator)

[@lucydeniss3115]

I didn't not understand well on the calculating the prevalence

[@aaryanair6438]

How 855?

[@lukebonavia9939]

Did the pilot get his licence back?

[@jeskow19]

He worked for United. They just beat his ass.

[@avip9]

why aren't you blinking
