 
Bivariate Oddities

This apLet contains four data sets, all radically different, which all
have the same summary statistics (mean, variance, correlation, etc.). 



The idea is to show students that the summary stats are not the end of
the story  that a graph is still a good idea, as is looking at the
residuals. 
Chain Rule
This apLet contains a number of prepared sets of functions of increasing
complexity. 

With the apLet is a worksheet on which the student records the result of
differentiating the functions using the algebraic differentiation
capabilities of the Function apLet. 

With a bit of luck, the student should be able to deduce the Chain Rule
from viewing the common behaviour of the derivatives.
