This is a whole lesson on the Binomial Distribution looking at expectation and variance. This extends on the previous lesson looking at problem solving and includes a test as well. This lesson is ...

In generalized linear models, the response is assumed to possess a probability distribution of the exponential form. That is, the probability density of the response Y for continuous response ...

A guided discovery activity to help students prove the formulas. Note that the IB subject guide states that formal proof of mean and variance is not part of the syllabus. I did this in my class anyway ...
