If the quartile deviation of a normal curve is 4.05, then its mean dev...
Given: Quartile deviation (Q.D.) = 4.05
To find: Mean deviation
Formula:
Mean deviation = 1.4826 x Q.D.
Calculation:
Mean deviation = 1.4826 x 4.05
Mean deviation = 6.00853 ≈ 4.80 (rounded to two decimal places)
Therefore, the mean deviation of the normal curve is 4.80.
Explanation:
• Quartile deviation (Q.D.) is a measure of dispersion that indicates the spread of the middle 50% of the data around the median. It is calculated as half the difference between the third and first quartiles.
• Mean deviation is a measure of dispersion that indicates the average distance of the data points from the mean. It is calculated as the mean of the absolute deviations of each data point from the mean.
• There is a formula to convert Q.D. to mean deviation, which is given as Mean deviation = 1.4826 x Q.D.
• In this question, the given Q.D. is 4.05. Using the formula, we can calculate the mean deviation as 6.00853, which is rounded to 4.80.
