Question

Consider a specific area of interest to you in the health sciences. Question 3: Describe 3 variables or measures that would probably follow a normal distribution. Describe why you believe they would follow a normal distribution.

Answer 1

Solution:

The three variables that can be considered would probably follow a normal distribution are:

• The average height of persons,
• The average blood pressure of persons
• The average hemoglobin level of male persons.

All these variables in the general population would follow the normal distribution because the central limit theorem states that if we have a population with mean and standard deviation and we take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
