A sample of 50 readings has a mean of 75 and standard deviation 5. What is the coefficient of variation?

Explanation:
The coefficient of variation shows relative variability by comparing the spread to the mean. It is calculated as the standard deviation divided by the mean. Here, s = 5 and the mean x̄ = 75, so CV = 5/75 = 0.0667 (about 6.67%). It’s unitless and helps you compare variability across datasets with different scales. This value matches the provided result of 0.0667.
