Why picking only 10 people for a data study is worse than picking > 30 people.
Use some dice. The average value of any single die being rolled should be 3.5(that the average of 6,5,4,3,2 & 1). However when you roll it once it's very possible for you to get really far away from that 3.5 number.
The Short Answer
Use some dice. The average value of any single die being rolled should be 3.5(that the average of 6,5,4,3,2 & 1). However when you roll it once it's very possible for you to get really far away from that 3.5 number. Personally I just rolled a 6. That's super far away from that 3.5 we suggested earlier. Do you think rolling the die once was a good estimator? Probably not. Ok I just rolled again and got a 2. That's an average of 4, I got closer! Rolled again for a 1, that's average of 2.3, ouch we moved further away. Just keep rolling dice and judge how far away you are from the average after 10 rolls and 30 rolls.
