Answer 1

Textbook Question

Chapter 9, Problem 1RE

Determine whether each of the following statements is true or false, and explain why.

1. The mean, median, and mode of a normal distribution are all equal.

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.

Expert Solution & Answer

To determine

Whether the given statement “The mean, median, and mode of a normal distribution are all equal” is true or false.

Answer to Problem 1RE

The given stamen is true.

Explanation of Solution

Normal distribution is a bell shaped curve and it has only one peak at the centre of the distribution. The mean, median and mode are all equal in the normal distribution.

Therefore, the given statement is true.
