When reviewing the results of the survey, please keep in mind some of the following issues:
The results presented are meant to describe the overall pattern of the data. They do not take into account or "control for" any characteristics of the respondents. Although additional analysis can "control for" some of these effects, the current report presents an overall snapshot of the results due to the large number of possible variables.
Although the graphs may suggest differences among groups, in many cases these differences are not statistically – or meaningfully – different.
Differences that may be statistically significant may not be practically significant. Practical significance rests on judgments of whether a difference is relevant or of any importance in the real world.
In some cases, the number of participants in a particular group is small. Results from a smaller group of participants are less stable and reliable as compared to results from a larger group of participants.
