About the book

Building on the Foundations of Statistics is meant for students who have met some of the theory behind hypothesis testing and learnt how to apply a range of basic hypothesis tests using SPSS. The text aims to extend students' skills by introducing new concepts related to relationships and hypothesis testing. It also aims to develop the students' insights into the strengths and limitations of hypothesis testing. Students will be introduced to more advanced statistical techniques, namely, multiple regression and analysis of variance.
