Quantitative Data Analysis
In this chapter, some of the basic but nonetheless most frequently used methods for analysing quantitative data analysis will be presented. In order to illustrate the use of the methods of data analysis, a small imaginary set of data based on attendance at a gym is used. It is the kind of small research project that would be feasible for most students doing undergraduate research projects for a dissertation or similar exercise. The chapter explores: • the importance of not leaving considerations of how you will analyse your quantitative data until after you have collected all your data; you should be aware of the ways in which you would like to analyse your data from the earliest stage of your research; • the distinctions between the different kinds of variable that can be generated in quantitative research; knowing how to distinguish types of variables is crucial so that you appreciate which methods of analysis can be applied when you examine variables and relationships between them; • methods for analysing a single variable at a time (univariate analysis); • methods for analysing relationships between variables (bivariate analysis); • the analysis of relationships between three variables (multivariate analysis).
