What are the measures of variability?

1 answer

The measures of variability are:

1. Range: It is the difference between the largest and smallest values in a dataset.

2. Interquartile Range (IQR): It is the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset.

3. Variance: It is the average of the squared differences from the mean of a dataset.

4. Standard deviation: It is the square root of the variance and measures the amount of variation or dispersion in a dataset.

5. Coefficient of variation (CV): It is the ratio of the standard deviation to the mean of a dataset and is expressed as a percentage.

6. Skewness: It measures the degree of asymmetry in the distribution of a dataset.

7. Kurtosis: It measures the degree of peakedness or flatness in the distribution of a dataset.
