They aren't meaningless ether. Unless you're as nieve as Galton in 1906, and refuse to recognize averages because you want to commit the sin of confirmation bias because it contradicts your world view.
If you were right then a simple look to see if average scores of an individual would prove it. If I'm right then the average of their scores for what they reviewed would approach the overall average, and if you're right it wouldn't. Though you have to check users with a sufficient sample. I've check on several occasions. The data is public. Go verify for yourself.
Are you deliberately missing the point?
Obviously, since I disagree with YOU, I must have a confirmation bias.
I'm not saying averages are meaningless, I'm saying they're meaningless here.
No, your confirmation bias comes form your proclamation that averages should be ignored without data to back up your opinion. Or are you not a statistician as you claim? Which is what Galton did when he was desperate to prove that people as a whole are stupid. Your view isn't that much deviant from his since you desperately want to prove that gamers who give their opinion are all "stupid fanboys". Your bias is clearly spelt out, and your reasoning for dismissing averages is not.
What, pretel, do you think is different a bunch of random people writing down how much meat a cow will produce after it goes though the butchers versus asking people what rating do they think a game is? I'll get back to this. Just think about it.
Since you're clearly incapable of doing the math to prove your point let me show you, and anyone else who happens to be reading in on how this works.
Lets take the first user who reviewed Sonic Lost World on metacritic who reviewed more than 1 game. Our lucky reviewer happens to be MrAwesome091 [http://www.metacritic.com/user/MrAwesome091].
The users scores are
9,8,3,1,8,2,6,7,6,8,10
and the overall user score for each game is
8.2,7.4,2.2,1.4,7.5,7.7,3.6,7.3,6.0,7.7,8.0
MrAesome091's average comes to 6.2 and the average of all the games he reviewed came to 6.09. Now I know you are under the nieve impression that is the definitions of average. You are incorrect. This only works if two statements happen to be true. MrAesome091 must be giving is own personal view of what the game should be rated as. If he was being paid to give positive scores this wouldn't work. Second the average scores for each game cannot be biased significantly by anyone being paid to give a good review. Though also the converse could be true with him being paid, and all the scores being biased by publishers and devs. However, If a score of 2.2 is what the publishers are trying to create they're insane. Logically publishers would really only pay for positive scores.
I've given sufficient proof that the average scores are not significantly biased by paid astro turf, and that MrAesome091 is a fairly honest reviewer.
Now what is the difference between
asking people their
opinion on how much
Meat a Cow will give
vs
asking people their
opinion on how
good a game is.
Outside of one is meat and the other is a game not much. Their both opinions, and can be averages if you get a score for "how good" something is. If in the opinion of the cow the average didn't matter then the average wouldn't come out to be anywhere near the actual result. It would be just as you paint it "meaningless".
You haven't got to Galton in statistics so you're still fresh, but do you now what his experiment to prove that people ware stupid when he took all their guesses at how much meat a cow would produce? The Crowd guessed that the amount of meat that the butcher would get off of a cow to be 1,197 pounds. Galton didn't want anything to do with averages so he used the data to claim that they were stupid. The cow generated 1,198 pounds.
Averages are the only way to remove the "fanboy" bias your so hung up on. You should probably brush up on your stats. Your students will be better for it.
