For a given set of radiance values, which amongst the following is/are unitless?
Show Hint
- Skewness
- Kurtosis
- Mean
- Standard Deviation
The Correct Option is A, B
Solution and Explanation
- Mean is a measure of central tendency, and it has the same unit as the radiance values.
- Standard deviation measures the spread or dispersion of the data, and it also has the same unit as the radiance values.
Step 1: Understanding the measures. - Skewness is used to measure the asymmetry of the distribution of values around the mean.
- Kurtosis is used to measure the "tailedness" or sharpness of the peak of the distribution.
Step 2: Conclusion. Since skewness and kurtosis are dimensionless, they are unitless, making options (A) and (B) the correct answers.
Thus, the correct answer is (A) Skewness, (B) Kurtosis.
