I am currently doing my undergraduate thesis for psychology. I noticed in my data collection when asking the participants age i asked it wrong e.g. 18-21,21-25. Age is not one of my variables i am testing in this study and will have no implication on the results of my study. If i acknowledge this as a limitation and state how it wont impact results will this still have a big impact on my grade?

  • Only the instructor of your course can decide what will and won't impact your grade, though I can't see much reason for something like this to matter. I do think it's kind of a weak limitation to point out, though, in my opinion you'd be better off finding more interesting weaknesses that actually impact your results, I promise you that your study has some because every study does. – Bryan Krause Jan 18 at 16:32
  • Consider not mentioning age at all in your thesis; information you collected but didn't use isn't really relevant and is not a limitation. Then you can include an appendix with the full text of the survey. In this case, I really can't imagine it would affect your grade at all even if they did notice the mistake in the appendix (though of course, only your professor's opinion counts). – cag51 Jan 18 at 17:12

If age is not a variable used in the later analysis, then it cannot be wrong.

If you should have included age in the later analysis, then that may cost some points - depends on what they are looking for...

Including age in the original survey is usually a good thing as it means that that data may be suitable for different variations of studies ie the data is possibly more useful.
