This was just a very quickly thrown together questionnaire, as you have all been able to tell. For a module unrelated to my project but the survey has to be about the project. We get marks if we do a survey and interpret the results. So as long as I say that all the questions were biased and what I would change for next time, it's all good. There is no decision justification in the survey, it's purely a standalone piece of data gathering.
A poor job is something to be held up in front of the class as an example to others - rather like the videos we are shown of bridges collapsing. Not something to be awarded high marks.
Following this up with a report which explains why the results are worthless is like building a bridge and then producing a report which explains why it'll collapse in high winds.
We are engineers, you and I. We are the people who DO understand basic arithmetic, who CAN perform a rational analysis of products we are offered, and who absolutely SHOULD be teaching others how to do the same. Because if we won't do it, who will?
Go back and start again. Some better questions might be:
- Have you ever worked out how much you might be able to save on your electricity bill by installing solar panels?
(Gathers information about someone's prospective level of interest, without leading them either way)
- Do you have the authority to make the decision as to whether solar panels could be installed where you live?
(Critically important commercial information; if someone rents their property or is subject to planning restrictions, the question of installing solar panels is academic no matter how good they are)
- Would you be interested in a system which, on average, improves the output of a solar installation by 10%, if that system increased the cost of the installation by 15%?
(Honest and quantitative - allows someone to make an informed judgment based on real figures and their own preferences for cost vs benefits of using renewable energy)
