Histogram
The maj
ority of cases are clustered at the lower end of the scale, with most falling
below 100,000. There are, however, a few cases in the 500,000 range and beyond (too
few to even be visible without modifying the histogram). These high values for only a
few ca
ses have a significant effect on the mean but little or no effect on the median,
making the median a better indicator of central tendency in this example.
