Money and time are both limited at the charter school. Jill, the director, sent out a survey of parents' perceptions of purchasing priorities for the school. She had a group of parents respond to the questionnaire as a pilot. She had them rate their priorities on a rating scale with the points "necessary," "very important," "purchase if money is available," "not necessary," "don't purchase."
She was disappointed to find that the pilot parents rated everything as necessary. This will not help her make purchasing decisions. Of the following, what is the best strategy for Jill?
◦ Revise the instrument to include open-response items to get richer data.
◦ Conduct in-person interviews with the same items.
◦ Revise the instrument so parents must rank items to purchase relative to each other.
◦ Send it out as it is. The larger general population of parents will have more variance than the small pilot.
