observations using behavioural categories. Content analyses can also collect quantitative data. These data can be interpreted fairly easily with averages‚ measures of dispersion and graphs (pages 52–53) and are typically objective. Qualitative data are descriptive‚ e.g. answers to open questions from self-reports (page 41) and detailed findings from observations and content analyses. They are harder to analyse as you need to look for
