•It is bell-shaped
•The mean, median, and mode are equal and located at the center of the distribution
•It is unimodal (only has one mode)
•It is symmetrical about the mean
•Which is the same thing as saying that its shape is the same on both sides of a vertical line passing through the center
•It is continuous – There are no gaps or holes
•The area under a portion of a normal curve is the percentage of that data that falls between the data values that begin and end that region (we will talk more about this don’t worry)
•The total area under the curve is exactly 1.
