The arithmetic mean of the different deviations observed in several measurements of the same quantity is known as
Correct answer: B. The average deviation
- A. The standard deviation
- B. The average deviation
- C. Relative mean deviation
- D. Variance
Explanation
This is the definition of average deviation. It is calculated by finding the absolute difference of each measurement from the mean, summing these differences, and then dividing by the number of measurements.

About Analytical Chemistry
Analytical chemistry identifies and measures substances using separation and instrumental methods. Chromatography is studied through stationary and mobile phases, retention and Rf values, while spectroscopy connects absorption of electromagnetic radiation with molecular structure and supports qualitative and quantitative analysis through techniques such as UV-visible and infrared spectroscopy.
