Outstanding explanation! Thanks for sharing
you really know how to drag a concept out.
+97GoldDust Thanks, not sure if that is a compliment or not. Haha. My students tell me the same. I am working on me new videos being shorter and less winded.
Michael Porinchak but how do you mathematically draw a curve, do u just draw one with free hand or is there an f(x)?
what will happen if you add values to the tail ends of the normal distribution? will it change the standard deviation?
+Angie Lim If a lot of data were added to a tail then the mean would be forced to move towards that data and then well it no longer when be data far out on the tail. Hope that makes sense. Basically if a bunch of outliers were added then they no longer become outliers because the mean and standard deviation has to adjust for them.
A very good and thorough explanation, thanks a lot.
Help so much! Thank you
