Question
Measure of dispersion called as mean deviation, is based on ________.
Select one:
- a. Normal deviations
- b. Squared deviations
- c. Cubic deviations
- d. Absolute deviations
Solution
Break Down the Problem
- Identify the meaning of mean deviation.
- Determine which type of deviation it is based on from the options provided.
Relevant Concepts
- Mean Deviation: This refers to the average of the absolute deviations of each value from the mean of the dataset.
Analysis and Detail
- Mean deviation is calculated using the absolute values of deviations, rather than squared or cubic values.
- This distinguishes it from variance, which is based on squared deviations.
Verify and Summarize
Based on the definition and characteristics of mean deviation, it is clear that it uses only absolute values of the deviations from the mean.
Final Answer
d. Absolute deviations
