Which one of the following is always true? Select one:
a. The coefficient of variation is a measure of relative dispersion that expresses the standard deviation as a percentage of the mean, for any data on a ratio scale and an interval scale.
b. The coefficient of variation measures variability in a positively skewed data set relative to the size of the median.
c. The interquartile range is very unique in the sense that it is a measure of central tendency as well as a measure of dispersion.
d. The coefficient of variation should only be used to compare positive data on an interval scale.
e. None of the suggested answers are correct

Which statements are INCORRECT?
Which statements are INCORRECT?If two data sets have the same standard deviation, they must have the same coefficient of variation.The number of standard deviations between the 25th percentile and the median is always the same as between the median and the 75th percentile.The range is considered the weakest measure of variability.The 5-number summary consists of the smallest observation, the first quartile, the median, the third quartile, and the largest observation.
