Excellent video. I never thought that i'd be able to understand biostats, but you made it possible. I will definitely be recommending this lecture series to my colleagues.

[@AzfarBasuniaMD]

Thanks so much for your kind words!!!

[@nataliyab4701]

thank you! great job! Found some typo: TN/TN+FP = Specificity, not Sensitivity

[@AzfarBasuniaMD]

Ah yes, thanks for the heads up! I blurred it out. Hopefully its not confusing now

[@AAhmed-sf7zp]

Dr Azfar is there a video of you explaining Box and whisker test ?

[@AzfarBasuniaMD]

I dont think I explained it in the video. Here's a really good summary from Khan Academy. www.khanacademy.org/math/statistics-probability/summarizing-quantitative-data/box-whisker-plots/a/box-plot-review

There is an error in this video... When going over the lung cancer PPV example, it was given as 90/450 which simplifies to 0.2, not 0.167.
