The Normal Distribution

• Properties of the bell shape curve
• Finding integral and non-integral probabilities {TI-84 Plus CE}
• Finding quantiles {TI-84 Plus CE}​

A normal distribution is a distribution of data that is symmetrical and bell-shaped, often referred to as a bellcurve. Although all normal distributions share the same bell-shaped curve, the exact shape and location of the curve is determined by the mean and standard deviation.
