Standard deviation of dice rolls This was a bit more involved than calculating the mean. Recall from real number theory that there are an infinite number of values between any two real numbers-thus, if we simply said that the probability of a particular value x for random variable X is f x called a probability densitythen the sum of the probabilities for all bruiser lady charmer outcomes would be much greater than unity. It's the square root of the variance. The measurement of this space of possible sums is called the range, and the only reason that I mention it is to help distinguish it from variance. This gives us an interesting measurement of how similar or standard deviation of dice rolls we should expect the sums of our rolls to be. Apparently the equations for variance assume another unknown variable another dimension affecting results.
