Survey Inaccuracies Survey Inaccuracies Ah statistics, one of the great lies of our world. Suppose you see an interesting class. It's 3.2, and you decide not to go. Let's say the attendance of that class was 100, and we got a 10 people from that class sent back their surveys, and it gets the low rating of 3.2 . Now suppose 5 other people sent in their surveys later, all giving the class a 9.
Different people have different opinions.
If a class gets two responses, one rating the class at 10, and the other at 1, the class gets a rating of 5. The point is, this data is not always accurate, and the comments people make about the classes tend to be much more valuble than the ratings themselves.
