How should we weight the relative influence of questions that have a high frequency of hits, but receive a small, but predominant number of ratings that indicate they are Not Helpful? So, if a question gets 3,000 hits in a month, and receives 3 ratings of Not Helpful - the question should be either revised or deleted? My intuition tells me, probably not.
Absolutely not, and that's not what I suggested. I would put this in category 2 (not 1, or 2b). I probably should have added:
2.d. little or no feedback, assume effective - leave alone
You're right, I didn't quantify. It's probably tough to do without seeing your data. Seems to me, to impement my sugesstions, you just need to determine some thresholds:
- low frequency threshold (when to delete)
- not helpful threshold (when to revise or supplement)
- helpful threshold when not helpful threshold is exceeded (to decide whether to revise or supplement)
I'd make the (not) helpful thresholds a percentage of hits, not a percentage of feedback. So, for your example, 0.1% not helpful ratings is not something I'd act on.
