Once data has been cleaned and processing errors checked, descriptive analysis can
begin. You should comment on the data collection procedure and construct appropriate
charts and plots to help you:

- identify any pattern in missing data;
- identify the shape of distributions;
- summarize each variable using appropriate descriptive statistics;
- present a summary of the data in the form of frequency tables that would be suitable for
inclusion in a journal article.
