Maths · Calculation of standard deviation, variance and mean deviation for grouped and ungrouped data
Which of the following are dimensionless
Which of the following are dimensionless
- A. S.D.
- B. М.D.
- C. variance
- D. coefficient of variation
Step-by-step solution
Standard deviation (S.D.) and mean deviation (M.D.) have the same units as the data, while variance has squared units. Only the coefficient of variation (S.D./mean) is a ratio of two quantities with the same units, making it dimensionless.
