A bell curve is a statistical graph shaped like a bell. It is used for several activities, such as finding percentiles or probabilities based on data you collect. Texas Instruments has a series of graphing calculators. Using these calculators, you can graph the bell curve. This is a good function to learn because it allows you to visually see your bell curve and you do not need to manually produce the curve.
