Explanation:
Detailed explanation-1: -Measures of spread include the range, quartiles and the interquartile range, variance and standard deviation.
Detailed explanation-2: -The interquartile range is the difference between the 3 r d and I s t quartiles. When we change to, the IQR remains unchanged because the first and third quartiles remain unchanged. As a result, IQR is resistant. As a result, the interquartile range is a spread metric that is resistant to change.
Detailed explanation-3: -The interquartile range is the best measure of variability for skewed distributions or data sets with outliers. Because it’s based on values that come from the middle half of the distribution, it’s unlikely to be influenced by outliers.
