To do this,find anything like you mentioned that has a survey. Now a survey must use ratios to get conclusion because you must first figure out how many people out of the entire group are divided to get an answer. Lets say you take a survey over ice cream. You survevy 40 people. 25 people vote vanilla,10 vote chocolate,and 5 vote strawberry. You would use these ideas to conclude that most people like vanilla and not very many people like strawberry. Hope this makes sense :)
