Normal Distribution (Bell Curve) Definition, Examples, & Graph

When you have a set of data that you think might have a normal distribution (i.e., a bell curve), a graph of your data can help you decide whether or not your data is normal.

Step 2: Divide the difference by the standard deviation. SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.

Probability plots for distributions other than the normal are computed in exactly the same way. The normal quantile function Φ is simply replaced by the quantile function of the desired distribution. In this way, a probability plot can easily be generated for any distribution for which one has the quantile function.
