WebbThe shape of distribution looks a bit like a "bell", but with some random fluctuations. The width of the bell, from shoulder to shoulder, seems to be around 40 (the majority of scores are in the range 480 to 520), and from foot-to-foot, around 100. All of the 1000 trials shown here have resulted in between ~455 and 555 heads.

"WebbThe standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution. " - Shape of a bell curve
