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. |
