Random story.

I remember, when I was at the HARD university.
I was failing about half of my classes. It was inevitable, that I'll drop out in this semester.

A girl comes to me with a survey.
Question one: What semester am I in: I anwsered 2nd.
Question two: When do you plan on finishing your study?
me: This semester.

Her: wow... Immediatelly types it in. Before she realizes what I meant, she couldn't change the anwser on her tablet...

This is the quality of data you get through surveys. XD
