This booklet contains hints to the solutions and answers where
necessary, of the exercises contained in 'Intermediate Statistical
Methods' by G. Barrie Wetherill. The following principles have been
adopted in dealing with the answers. (1) In some cases the answer is the
drawing of a graph, and this has been omitted. (2) In many numerical
exercises a considerable amount of 'data snooping', plotting of
residuals, etc. should follow the main sis. The inclusion of this
material would make the answer booklet far too long. (3) In some cases
there is a readily available reference from which the answer can be ob
ained, in which case reference has been made to this. It is not
necessary to work through every exercise, but it should be recognised
that the exercises are an integral part of the main text, and a
comprehensive grasp of the subj ect cannot be obtained without
attempting a substantial proportion of them. It is hoped that this
booklet will be of assistance in pointing the way, and providing a check
on the more vital calculations. The importance of numerical exercises
should be stressed, and it is here that Appendix B is of importance.
There is abundant material available there in many different fields of
application. Currently we are in the process of mounting a form of
Appendix B on a computer, together with accessing programs.
