I: Let me take a look at the survey. Wow, this looks great! The map of the median income by region is a great tool. Where did you find it?
H: Well, thanks! I read a lot of sources and just noticed this one in a small psychology journal called Modern Psychology. It’s more helpful than the photo I added, but I think the photo is just so interesting. It was in the newspaper last year during that huge wage strike.
I: It’s great. Probably not necessary, but it looks great. I don’t understand — what is WKRX’s involvement here?
H: Oh, the radio station agreed to sponsor the study if I play their station in the room.
I: Wow, interesting. So, you don’t have to pay for any of this?
H: Exactly.
I: Nice! Where did you get that idea?
H: Last month at the Psychology Club Council meeting someone talked about how easy it is to get sponsorship from local businesses, so I listened to their advice and called around!
I: I’ll have to remember that. Well, this all looks great. Good luck!
