Which of the following is not a measure of dispersion?
Answer Details
The measure of dispersion gives information on how spread out or clustered a set of data is. It quantifies the variability or diversity of the data values. Out of the options provided, the measure that is not a measure of dispersion is the mode. The mode represents the value that occurs most frequently in a dataset. It is not a measure of dispersion because it does not provide any information about how much the data values deviate or spread out from the mode. The other options provided are all measures of dispersion.
- Mean deviation: measures the average distance between each data point and the mean of the dataset.
- Range: measures the difference between the highest and lowest value in the dataset.
- Interquartile range: measures the difference between the upper and lower quartiles of the dataset.
- Standard deviation: measures how much the data values deviate from the mean of the dataset.
Therefore, the mode is not a measure of dispersion, while the others are.
