Compare measures of variation quick check connexus

Answer 1

Measures of variation describe the spread or dispersion of a set of data points. The two main measures of variation are range and standard deviation.

Range is the difference between the highest and lowest values in a data set. It is a simple measure of variation that is easy to calculate but may be sensitive to outliers.

Standard deviation is a more sophisticated measure of variation that takes into account the average distance of each data point from the mean. It provides a more precise measure of dispersion and is less sensitive to outliers compared to the range.

In summary, the range is a simple measure of variation that calculates the spread between the highest and lowest values, while the standard deviation is a more precise measure that considers the distance of each data point from the mean.
