7% on the observations will drop within 3 standard deviations of the mean, which corresponds on the interval (-three,three) in this situation. Although it may perhaps seem as though a normal distribution will not consist of any values beyond a particular interval, the density is definitely good for all values, . Data from any normal distribution may be reworked into data following the standard normal distribution by subtracting the mean and dividing via the standard deviation . Case in point Discover how the results of random coin tosses will get closer on the envisioned values (50%) because the number of tosses boosts.
