Graham Upton is a retired Professor of Applied Statistics, formerly of the Department of Mathematical sciences at The University of Essex. He has published numerous books, including The Oxford Dictionary of Statistics, Data Analysis: A Gentle Introduction for Future Data Scientists, and Understanding Statistics with OUP.

Those who need to know how to select, carry out and interpret tests for various standard hypotheses, together with an outline understanding of how the tests work and with some useful warnings, will be well served by this book, and its inclusion of some material not usually found at this level will make it a useful reference.
