You want to use numerical summaries to describe a distribution that is strongly skewed to the left. Which combination of measure of center and sprea would be the best ones to use?
• Median and range.
• Mean and interquartile range.
• Median and standard deviation
• Median and interquartile range.
The best combination of measures to use for a distribution that is strongly skewed to the left would be the median and the interquartile range. The median is a robust measure of central tendency that is not affected by extreme values in the data, making it ideal for skewed distributions. The interquartile range is a measure of spread that is also not influenced by extreme values, making it a better choice than the standard deviation or range for describing the variability in a skewed distribution.
