normalpdf, normalcdf, and invnorm

[@raqad4642]

Thank you so much sir your explanation is incredible and I am really appreciative of that

[@donnapodhurst6552]

Some will understand when all they are told is ''''use technology'''' it just does not cut it----- and a good explanation DOES. ---- T.Y. for the good explanation.

you saved me so much time thank you and God bless you!!!

Actually, normalpdf finds the percentile for a particular z-score. Basically, it finds the area made to the left. It doesn't give the height, it gives area.

[@MrDaveblev]

normalCdf gives the AREA between given z scores. normalPdf gives the height in a corresponding normal probability density function, which is what the pdf stands for.

Oh wait, I get it now.

Why en when would you use normalpdf?

[@MrDaveblev]

As mention at about 7:49 in the video, it isn’t used for anything more than precise graphing. I guess, by the fundamental theorem of calculus, it could be used as a rate of change in probability accumulating, but that isn’t really practical either, that I am familiar with.
