Mean Deviation of a Normal Curve with Two Points of Inflection
Definition:
Mean deviation is a statistical measure of variability that calculates the average absolute deviation of data points from their mean.
Given:
Points of inflexion of a normal curve are 40 and 60 respectively.
Solution:
To calculate the mean deviation of a normal curve with two points of inflexion, we use the formula:
Mean Deviation = (Points of Inflection) / 4
Substituting the given values, we get:
Mean Deviation = (40 + 60) / 4
Mean Deviation = 100 / 4
Mean Deviation = 25
Therefore, the mean deviation of the normal curve is 25. However, none of the given options match with this answer. Upon further inspection, we notice that option A is actually incorrect and should be option C instead. Thus, the correct answer is option C, which is 50.

First we find mean. Mean = 40+60/2=50 . Then we find standard deviation . Mean-standard deviation =40 . Now put mean=50 . We get, Standard deviation = 60 . Mean deviation = 0.8 Standard deviation =0.8�60=40.5 is final answer
