great presentation! Explains things that you normally do not find in similar talks. For example it explains nicely where the term "density" in "probability density"comes from. It also differentiates "probability density" from "probability" for continuous variables. Finally, it makes it easy to see that for continuous variables, the probability to get an exact value (P(X=x) ) is zero (because a point does not have a surface, or class width = 0).

What an excellent explanation! Very well done. Thank you.

Thank you so much! You are a blessing.

how did you get 5 and 15?? :(

I'm confused. I am doing AS level Mathematics and the graph i have always draw simply has the y axis labeled as "Frequency divided by Class width". The part about relative frequency and relative frequency density really confused me. Is it just another way of explaining the same thing?? Aid please.
