The quartile deviation of a normal distribution with mean 10 and standarddeviation 4 is(a) 0.675.(b) 67.50.(c) 2.70(d) 3.20
Question
Solution 1
The quartile deviation, also known as the semi-interquartile range, is a measure of statistical dispersion. It is half the difference between the upper quartile (Q3) and the lower quartile (Q1).
For a normal distribution, the quartiles can be calculated using the z-scores for the 1st quartile (Q1) Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
