Start with a normal distribution with mean μ and standard deviation σ. You can observe such a thing begin to form with a simple pachinko board: the balls tend to collect in the middle and less so further from the middle.
The standard normal distribution Z is invented to have mean zero and standard deviation 1. You may standardize your normal data x with Z=(x-μ)/σ.
