Done. Good luck.
Assuming that he has a narrative as part of the assignment, a few suggestions (force of habit - I taught stats/epi at both undergraduate and graduate levels):
- Not knowing how/where he got his other respondents, suggest that he include the fact that many (most?) of his respondents were found through online communications as a possible bias in his results.
- Also that people may have defined "technology" differently since no definition was given
- Consider response distribution before picking a graph type (I love me a pie/doughnut but they can hide a lot of information)
