Wisdom of Crowds exercise with our Fund Raiser

Ok, ok, before you read this and say this guy needs to get a life, I already know.

We had a fund rasier at work were people had to guess the number of candies in a jar. After it was over, just like in James Surowiecki's book the "Wisdom of Crowds", I took all the guesses and did some analysis. The results;

• total number of estimations 104 (so it wasn't a big fund raiser)
• the correct number 567
• the average of all estimations (the crowds estimate) 515
• number of people better than the crowd 12
• number of people worse than the crowd 92

The crowd was better than 88% of all the estimates.
