Question

For a given set of radiance values, which amongst the following is/are unitless?

• A. Skewness
• B. Kurtosis
• C. Mean
• D. Standard Deviation

Hint:

Skewness and Kurtosis are unitless statistical measures that help describe the shape of a data distribution.

Answer 1

The Correct Option is A, B

- Skewness and Kurtosis are statistical measures used to describe the shape of a distribution and are unitless because they are based on the normalized values of the data.
- 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.
