Question

which of the following are resistant measures of dispersion? select all that apply. a. range b. median c. standard deviation d. interquartile range e. variance f. mean

Explanation:

A resistant measure of dispersion is not affected much by extreme values. Range is highly affected by outliers as it is the difference between the maximum and minimum values. Median is a measure of central - tendency, not dispersion. Standard deviation and variance are based on the mean and are influenced by extreme values. Mean is also affected by outliers. The interquartile range (IQR) is the range of the middle 50% of the data and is resistant to outliers.

Answer:

D. Interquartile Range
