1 | So a better model is tossing coins a 1000 times. |
2 | Shift over coin toss by 200 so results lie in range 201..1200 as in the Dice accumulation. |
3 | Now the frequency distribution is narrower. |
4 | It is still a beautiful bell shaped Gaussian but the percentage error is 1.6% not 2.4%. |
5 | You will get better answers from asking 1 person from 1000 households rather than 5 people from each of 200 households. |
6 | Actually Dice are not a very good representation of polling, as a result with 1000 cells corresponds to only 200 Dice |
7 | This is like polling where you went to 200 households and asked 5 people in each household. It is not 1000 independent samples. |
8 | +16 |
9 | -16 |
10 | 700 Mean |
11 | 1000 Tosses Count Number of Heads |
12 | Add 200 |
