Note that the PROBPLOT statement creates a normal probability plot for DIAMETER by default. The nonlinearity of the point pattern indicates a departure from normality. Since the point pattern is ...

Below are two probability plots for his two sets of data. Notice that one can be considered normal while the other is not. If ...

One of the most common applications where log-normal distributions are used in finance is in the analysis of stock prices. The potential returns of a stock can be graphed in a normal distribution.

Well log analysis uses the Porter et al. plot. It requires plotting a parameter P =[R t (Δt – Δt ma) m] 1/2 or P =[R t (ρ ma – ρ b) m] 1/2 vs. cumulative probability on normal-probability ...

Here is an example of a plot for a pair of standardised level 2 residuals from a repeated measures data set: The x-axis refers to intercept residuals and the y-axis to slope residuals. Here are Normal ...

Figure 2: Q–Q (normal probability) plots compare the differences between two distributions by showing how their quantiles differ. ( a ) Probability plots for n = 40 noise samples and their box ...

The cutting process is in statistical control. As a preliminary step in a capability analysis of the process, it is decided to check whether the distances are normally distributed. The following ...
