Stem-and-leaf plots are considered a geovisualization type map. They can tell you how the variable is distributed in the population. For example, this stem-and-leaf plot of student marks is fairly symmetric with short tails although there was also an outlier. To understand the values represented, you take the number to the left of the bar and place each value in the horizontal row next to that value. For example, the first row of numbers represented is: 90 and 96.Wednesday, July 16, 2008
