Choosing appropriate statistical tools for quantitative data at hand is a very important part of Research conducting, since one is going to draw conclusion after the analysis. If one is not competent enough to choose appropriate statistical tool for data at hand,the generalization drawn will be completely flaw. I think this book contributes more to solve the problem of choosing appropriate statistical analysis tool. To enhance the contribution of the book, I have also added SPSS applications of each statistical analysis tools. So, any one who is using this book will be advantageous in two important aspects. First he/she will be capable enough to choose an appropriate statistical tool for analysis. Secondly, he/she will be able to run the statistical analysis tools using SPSS by his/her own. Carrying out SPSS analysis is not an end by itself. You need to draw conclusions from the analysis, so does the book. This book is primarily designed for post graduate students who are expected to conduct quantitative data analysis in order to draw conclusions. In addition, statistic students, research practitioners can use most out of it.
