Quantiles

The Quantiles report lists selected percentiles for each level of the X factor variable. The median is the 50th percentile, and the 25th and 75th percentiles are called the quartiles.

The Quantiles option adds the following elements to the plot:

• the grand mean representing the overall mean of the Y variable

• outlier box plots summarizing the distribution of points at each factor level
