Box Percentile Plot
This is a new addition to my diagnostic tool kit. I had never used Box Percentile plot before. However this week, I had to look at outliers in a data. Histograms are not that good for outliers. Box Plots, same story(though whiskers in the box plot are useful in getting an idea about the data points 1.5 IQR away from the boxes). I usually prefer Box plots for the simple reason that it gives a sense of the data from a quartiles perspective.
