Actually I have no idea, how this video is factually correct, far as I know my text says you get expected values by multiplying say 120 x 80/380 to give 21.05, so what's the logic here? Please remake the freaking video! You don't explain assumptions like how you use 21% for a completely diff column!

80 out 380 DID fall sick, you did confuse us brah!!
Thumps up so he changes it!
-
By including the herbs when calculating your expected values, aren't you skewing the data toward non-significance?

heeerb heerb is plant mon. it help you meditate. JAH!
-
why do you say "erb", when its "herb"
-
Thanks for this. Just sorted my assessment for this week.
-
shouldn't you be squaring the numerator AND denominator?
-
great, what is your profession ??

What is this test good for? I dont get it. If herb1 and herb2 are unique, then you arent making a fair comparison by tossing in the placebo. And likewise if you want to test if either one herb does anything, tossing in the other throws off the data. I guess I dont see the scientific soundness of using this test for this experiment.
