Boxplot

The final piece of output from explore is the box and whisker plot. I have added an image after this paragraph for your understanding. This is a visual representation of the dispersion of values around the median.

The box contains the middle 50% of the values with a heavy line at the median. In this box plot, the line is at 13, which is the median value shown in the Descriptives table. The bottom of the box is at 12 and the top is at 16, which is consistent with the interquartile range value in the Descriptive table. The T or whisker lines above and below the box mark the boundaries of the typical or non-extreme portion of the values. As values are bound by 0-20 and the median is at 13, the upper whisker is shorter than the lower one.

Additionally, the extreme values are all at the bottom (the 17 individuals who reported 5 or fewer years of schooling) of the range. The case numbers in the data for the extreme values are displayed on the graph if there is sufficient space to do so. Here, 16 of the 17 fit on the graph. These numbers correspond to the row in the dataset with the associated value for this field:
