    Dear Dr. Grande thank you very much your explanation, which make it quite easy for me to understand the Box & whisker plots.
    However, if it is not too much bothering, I would love to ask for your guidance on "how to draw data points on box and whisker plots in excel 2016". I want to show my data points on box and whisker plots but couldn't do so.

    In your above example, lets say those 50 data points are for different people(Assume names to be 1-50). Now when I hover over outliers, would it be possible to show the person name(1-50 in this case). Right now it shows the value.

    What is the benefit of inter quartile for analyzing data?

      To identify outliers, put the IQR into this formula, 1.5 * IQR +/- Q (1 or 3). You have your Q1 and Q3, 25th percentile and 75th percentile, you can get them using the cell formula in excel. Any numbers outside of this range is outlier.
