How to Do a Bell Curve on a TI

By Carter McBride

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.

Press "1."

Type "X,0,1)." These set your bell curve up for a normal distribution. The X is your variable. The 0 is your mean and the 1 is your standard deviation.
