Where the statistics are found matters too!
The place where a survey is taken can affect the statistics. Many people use this to their advantage when wanting to prove a point.
Ex: I am in strings and I wanted to make a graph showing which students prefer; band or strings. Would the graph be affected if I took the survey in strings class? Yes, probably because everyone in strings would like strings, so the graph would reflect that.
