... Histograms are not always the greatest way to check distributional shape. In fact, the pattern can change quite a bit when you change the histogram boundaries just a little. To augment this view, we will use quantile-quantile plots. We will plot the empirical quantiles of Xbar1 or Xbar5 or Xbar30 ag ...

... If σ is a permutation of {1, . . . , 11}, we will denote by <σ> the product of the entries Mi,σ(i) times the sign of σ; thus the determinant D is the sum of <σ> over all σ. Of course the expected value of <σ> is 0 and its variance is 1; moreover, for distinct σ and τ, <σ> and <τ> are independent sin ...

Law of large numbers
In probability theory, the law of large numbers (LLN) is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large number of trials should be close to the expected value, and will tend to become closer as more trials are performed.The LLN is important because it ""guarantees"" stable long-term results for the averages of some random events. For example, while a casino may lose money in a single spin of the roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. It is important to remember that the LLN only applies (as the name indicates) when a large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be ""balanced"" by the others (see the gambler's fallacy)
