A dot plot is a type of graphic display using filled in circles (dots) and a simple scale to compare the counts (frequency) within categories or groups, when working with small data sets with a small number of groups.
The histogram, dot plot and box plot in each separate section represent the same data set. Symmetric (bell shaped) - when graphed, a vertical line drawn at the center will form mirror images, with the left half of the graph being the mirror image of the right half of the graph. In the histogram and dot plot, this shape is referred to as being a bell shape or a  mound . The most typical symmetric histogram or dot plot has the highest vertical column in the center. This shape is often referred to as being a normal curve  (or normal distribution).
