he was just laying out the broad idea here… I thought it was very clear. Very abstract though so people might be dealing with the fact that it's simplified to the point where its completely disconnected from anything they can imagine? I just took the trafic light example and stuck with it. I dunno I thought it was excellent
wat
For D Strategy, shouldn't it be -1 instead of 1? d' – B is 1 – 2 = -1. Not sure why he made it positive…
Not their best …
So… what was the point of all of this?
Can anybody explain why you have to lnBeta?
Definitely review this video. Saying it sucks is an understatement. It's way too confusing.
just gonna take the L on this video
if D strategy is d'-B, and you're saying d' is 1 and B is 2, then why is it 2-1? it would be 1-2…
bad video.
ronald are you good my man?
He seemingly chooses B arbitrarily then uses it in the equation for D, so the meaning behind the equation for D is lost.
Also based on his explanation an ideal observer is a liberal observer since 0<1. Very confusing.
Made complete sense to me. It goes much more in depth into signal detection theory than the Kaplan MCAT series so I don't know how much stock I should put into this video but still, it fills in some gaps left by Kaplan's overly broad review.
decent explanation, what y'all guys complaining about lol
barely audible on laptop full volume ….
Please improve audio quality
i do not know what is so confusing here….
that good feel of coming here to learn but getting more confused
this guy should not be allowed to make videos… i have seen his other videos and they are very confusing also…
That was horrible
This is a terrible video and not applicable to how signal detection theory would be tested on the MCAT. As someone who was a psych major and took multiple statistics classes, I've never heard it explained this way and i'm actually more confused now.
Is there no difference in the amplitude"
