Students are invited to investigate this with the aid of regression models. Emphasis is placed on the modelling cycle and particularly on model validation. Probability Models Issues of pollution control in a pharmaceutical company raise problems of simple probability distributions and modelling. Problems may be selected from a menu of six as directed by the tutor. Distributions include Binomial, Poisson and Normal.
Emphasis is on the process of modelling rather than on a tutorial in probability.
A Visual Approach Data are available on annual rainfall over 50 years at different locations across the Pennines. Students are invited to investigate the differences in the characteristics of daily rainfall in relation to altitude and longitude. This involves considering the accuracy of the data and handling different units of measurement. The raw data are simplified and presented graphically as histograms or stem and leaf plots. Animation is used to illustrate the construction of these, including the 'drag and drop' options for the student.
