Question

Examine the normal quartile plot and determine whether it depicts sample data from a population with a normal distribution

Does the normal quantile plot depict sample data from a population with a normal distribution?

A. No. The points do not lie close to a straight line
B. Yes. The points are evenly distributed above and below the mean, 0
C. The points exhibit some systematic pattern that is not a straight-line pattern
d. Yes. The pattern of the points is reasonable close to a straight line.

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.
