5  Appendix A - Data analysis methodology

1.  The response rate for this survey was 44%. Thus some caution should be used in interpreting the results across the population as a whole.

2.  The initial data set generated from the survey responses was cleansed for differences in formatting and input errors. Not all respondents answered all questions. The number of responses is shown on each graphic or table. Our policy when analysing these results has been to include in the analysis all valid responses to each given question. This might mean that, for example, the population of respondents to question 2 differs slightly from the population of respondents to question 3. Where we performed calculations which draw from responses to more than one question, we only included responses which answered both questions. When making comparisons between years or where more than one question is used in a piece of analysis, only completed data sets have been included.
