Bell shaped bar graph.
This distribution is called a NORMAL frequency distribution with the corresponding curve called the NORMAL (or bell-shaped) CURVE. In this scenario, the mean ,median, and mode all have the same value and a specific percent of the total data lies within one, two, or three standard deviations of the mean.
