How to read this plot:
A Normal Q-Q (Quantile-Quantile) plot compares the distribution of your data against a theoretical normal distribution.
- X-axis: Theoretical Quantiles from a standard normal distribution (Z-scores). (The histogram below shows this perfect bell curve).
- Y-axis: Sample Quantiles from the chosen data distribution. (The histogram on the left shows the shape of the data).
- Reference Line: The red dashed line connects the 25th and 75th percentiles (the middle 50%). If the blue dots fall closely along this line, the data is normally distributed.
Current State: Normal Distribution - Dots align with the reference line.
