So you want to ignore the part where you were wrong? I've taught statistics to undergrads and grad students. You are dead wrong and can leave the thread now. Probably best to not post for some time too. LOL, A) I am directly quoting my own professor who is Ivy League educated, and B) if you want to just google the word "average," what I said comes up almost immediately. As I said, "mean" is the generally used definition of average, but the mode and medians are still technically averages. Your professor is a moron if he told you that and google is not a source. Mode is the most frequent value Median is the exact middle value Mean is the statistical average. Bye bye now. Wow, you really think this is about not understanding the difference between mode, median, and mean? I'm definitely not suggesting that the mean and median are the same thing. This is about you guys not understanding the definition of an english word. ETA: M-W has them listed as synonyms as well. Is that not a valid source either? You know better than the dictionary? This is laughable. Also yeah, my teacher who got his PhD from Columbia and is a professor at NYU is an idiot, you're right. ETA2: Also, just because you are being a dick, If you really want I can email you copies of my perfect score on the math section of both the SAT and ACT to prove I understand the concepts of mean, median, and mode.
