Properties of Normal Distribution: (3p)

Write the word or phrase that best completes each statement or answers the question.

a. What is the total area under the normal curve?

b. The normal distribution is defined by two parameters. What are they?

c. What are the mean and standard deviation of the standard normal distribution?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
