1. Mean Deviation measures:
Answer: B
Mean Deviation is a measure of dispersion. It shows the average distance of observations from a central value like mean or median.
Mean Deviation is a measure of dispersion. It shows the average distance of observations from a central value like mean or median.
2. Mean Deviation is also called:
Answer: B
Mean Deviation is commonly known as Average Deviation because it is the average of absolute deviations.
Mean Deviation is commonly known as Average Deviation because it is the average of absolute deviations.
3. Mean Deviation is taken from:
Answer: C
It can be calculated about Mean or Median. However, it is minimum when calculated from Median.
It can be calculated about Mean or Median. However, it is minimum when calculated from Median.
4. Absolute deviations ignore:
Answer: B
Negative signs are ignored so deviations do not cancel each other.
Negative signs are ignored so deviations do not cancel each other.
5. Mean Deviation about Median is:
Answer: B
Median divides data into two equal halves, minimizing total absolute deviations.
Median divides data into two equal halves, minimizing total absolute deviations.
6. Formula of Mean Deviation (Individual Series):
Answer: B
Mean Deviation equals sum of absolute deviations divided by number of observations.
Mean Deviation equals sum of absolute deviations divided by number of observations.
7. It is based on which average?
Answer: C
Mean Deviation can be computed from Mean or Median depending on requirement.
Mean Deviation can be computed from Mean or Median depending on requirement.
8. Mean Deviation uses:
Answer: B
It considers only absolute values of deviations.
It considers only absolute values of deviations.
9. Coefficient of Mean Deviation =
Answer: A
It is a relative measure calculated by dividing Mean Deviation by Mean or Median.
It is a relative measure calculated by dividing Mean Deviation by Mean or Median.
10. Mean Deviation is a:
Answer: A
It is expressed in the same units as the data.
It is expressed in the same units as the data.
11. Lower Mean Deviation indicates:
Answer: B
Smaller deviation means values are closer to the average.
Smaller deviation means values are closer to the average.
12. Mean Deviation cannot be:
Answer: C
Absolute deviations are always positive.
