The z-score is normally distributed, with a mean of 0 and a standard deviation of 1. It is known as the standard normal curve. Once you have the z-score, you can look up the z-score ... WebFeb 17, 2024 · Figure 1: Normal Distribution. From the above graph, you can see that the distribution is mostly about the mean or the average of all heights. Apart from this, most data is around the mean. As you move away, the probability density decreases too. This kind of curve is called a Bell Curve, and it is a common feature of a normal distribution.
