Should You Report Standard Deviation with Median or Use Interquartile Range?

Learn why standard deviation isn't reported with median and when to use interquartile range for data spread representation.

54 views

No, you typically do not report standard deviation with the median. Instead, use the Interquartile Range (IQR), which better represents the spread of data around the median. Standard deviation is more appropriate when reporting the mean since it measures the spread of data points around the mean, not the median.

FAQs & Answers

  1. Can I use standard deviation with the median? Standard deviation is not typically reported with the median because it measures spread around the mean, not the median. Instead, use the interquartile range for median data.
  2. What is the best measure of spread to use with the median? The interquartile range (IQR) is the best measure of spread to report alongside the median since it reflects the middle 50% of data around the median.
  3. When should I report standard deviation? Standard deviation should be reported when summarizing data using the mean, as it measures how data points spread around the mean value.
