To explain: The characteristics of the normal curve and determine the human behavior, trait or characteristic that is distributed normally and why they are distributed normally.
Answer to Problem 1TP
The three characteristics of the normal curve are (1) mean, median,
Explanation of Solution
A
- The values of mean, median and mode are same
- The curve is bell-shaped. Also, it is symmetric about the mean.
- The area under the normal curve is one.
- The normal curve do not touch the x-axis and it extends farther away from the mean on either sides
The few examples of human behavior which are distributed normally are described below,
Example 1:
The height of the population is distributed normally because the number of persons with extremely short height is very less as compared to the normal height as well as the number of tall persons in the population is also very less.
Example 2:
The weight of the population is distributed normally because the number of persons with extremely light weight is very less as compared to the normal weight as well as the number of heavy weighed persons in the population is also very less.
