FAQs
Q: What does a high coefficient of variation indicate?
A: A high coefficient of variation suggests greater variability relative to the mean, indicating higher dispersion in the dataset.
Q: Can the coefficient of variation be negative?
A: No, the coefficient of variation cannot be negative, as it represents a relative measure of variability expressed as a percentage.
Q: How is the coefficient of variation interpreted?
A: A lower coefficient of variation indicates greater relative consistency and reliability in the dataset, while a higher coefficient of variation suggests greater variability and dispersion.
Q: Can the coefficient of variation be used for comparing datasets with different units?
A: Yes, the coefficient of variation is unitless, making it suitable for comparing variability across datasets with different units of measurement.
Q: Is the coefficient of variation affected by outliers?
A: Yes, outliers can influence the coefficient of variation, particularly in small datasets. Robust measures of variability may be more appropriate in the presence of outliers.
