Question

robust design is to do with reducing the variation in performance. this variation can be measured as ?
1. standard deviations
2.absolute deviations
3.all of above
4. none of above

Answer 1

The correct answer is option 1 - Standard Deviation.

Standard deviation measures the variation in performance.

It is a statistical tool and calculates the sum of mean related variations in a data set.

Standard deviation can be calculated on sample data or the complete size of the data set.

It is the most effective for recording variations in performance.

Answer 2

Robust design is to do with reducing the variation in performance. This variation can be measured as Standard Deviations.

Standard Deviation is a measure that summarize that how closely the values in the provided data set of measurements is linked to its mean value. the closely the values are packed, the smaller is the standard deviation.

Hence,

Option 1 Standard Deviation is the right answer to the question above.

Thank you for asking. I hope the answer helped.
