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 :)
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!
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.
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
I cannot believe that I very easily could understand it all clearly by watching your video only 1 time , I cannot thank you enough😊
crammed this 3 hours before an exam. Thank you.
Will definitely get back to it from time to time.
Hi @darlenegnilo-dimaculangan6177!
Did you pass! :)
Really helpful clip to understand the relationship between prevalence and PPV! Thank you!

Now calculate the covid test.....
You will be shocked😂😂
Great, GREAT video. Clear and concise explanation. (And it reveals “bureaucratic medicine” and all its dangers. I know...I’m a pilot.)
So much better than the explanations I got in class. Thank you.
Maza aa gaya bhai.
Kya video banaya hai❤

Thanks. You just saved me the stress. God bless you
Nice presentation - it's especially useful to use simple Bayesian networks to do some of the heavy lifting in calculating these figures.
Nice . . . I just shared this with my Statistics class!
This was really well explained. Thank you, sir.
Very helpful. Thank you so much!
Thanks! Making PPV easy!
ahh helpful
what a wise explanation
A very informative clip, the interpretations are well captired.
best video ever
I feel just like it's amazing i know how to calculate it while I don't before..
excellent video. Thank you.
Very helpful video! Thank you :)
Great explanation!!! Thank you

Bingo !! But no one seems to care ...
That was a great video, you can explain very clearly, sir. Thank you!
great visuals
yo whhere you get the 240
Correlation between prevalence and positive predictive value
How we can calculate the prevalence P(D) if we didn’t get it?
thank you so much ^-^
thank you
Beautiful !
can someone help me please how can i caculate the prevalence of the desease ?
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
He's summing it up beforehand(e.g for first one he adds the 180 and 60 before to get 260 as the denominator)
I didn't not understand well on the calculating the prevalence
Did the pilot get his licence back?
He worked for United. They just beat his ass.
How 855?
why aren't you blinking
