Answer (1 of 4): In statistics, the standard score z is the number of standard deviations by which the value of a raw score x is above or below the mean value of what is being observed or measured: z = (x-)/ The probability that z is between values of 0.43 and 0.72 is 0.0978. Central Limit Theorem In the previous section, we demonstrated that if we repeated our 10-toss trials many, many times, the average heads-count of all of these trials will approach the 50% we expect . I decided to run another test by calculating the probability between the median and max of a randomly generated sample, figuring it should converge close to 50%: And it's pretty close. You're modeling it with a kernel density estimator with a Gaussian kernel, and the kernel bandwidth is very high relative to the scale of the distribution and the number of available samples.
