How many points in a scaled question is “enough”? That’s a pretty common question in survey design. If you’ve spent some time with online market research surveys, you’ve probably noticed that they often have five points. “Please rate your satisfaction on a scale from 1 to 5, with one representing ‘not at all satisfied’ and five representing ‘extremely satisfied’.” Sometimes, though, you may see a 7-point scale instead of 5. Is 7 points an improvement? How about 11? Is higher resolution better? The answer is, “that depends”.
