The important values that best describe a normal curve are 4. There are standard deviation units at the baseline of a normal curve. 5. The curve of a normal distribution extends indefinitely at the tails but does not 6. The area under a normal curve may also be expressed in terms of or 7. The mean, the median and the mode of a normal curve are 8. A normal curve is used in 9. About _. % of a score distribution is between z = 0 and z = 1. 10. The skewness of a normal curve is 0 because it is a shape. IL Sketch the drawing of the given z-value and indicate the area under the normal curve.
