Data considerations for Symmetry Plot

To ensure that your results are valid, consider the following guidelines when you collect data, perform the analysis, and interpret your results.

The data must be numeric: You must have continuous data, such as the weights of packages, or discrete data, such as the number of customer complaints.
The sample size should be at least 25 data points: If the sample size is too small, you might not have enough data points to accurately show the distribution of the data. Interpreting a plot with too few data points may lead to incorrect conclusions.
