... The mean and standard deviation together are good descriptions of a set of scores. If the standard deviation is large, the mean may not be a good representation. Roughly 68% of a set of scores fall within ±1s, about 95% of the scores fall within ±2s, and about 99% of the scores fall within ±3s. This ...

... sr (sun-rain), state 3: rr (rain-rain). Let {Xn : n = 0, 1, 2, . . .} be a stochastic process with the four states above as state space. Suppose the chance of rain is 0.3 if it was not raining the two previous days, 0.5 if it was not raining the day before but was raining two days before, 0.6 if it ...
