# How does a median have a value that is a decimal which isn't exactly half of an integer if the data should consist of only integer values?

I real an article which said the average man accumulated 6.1 sexual partners while the average woman accumulates 3.6. If the statistic talked about the average, surely the numbers would be equal-so it must talk about the median. But how is the median 6.1 or 3.6?

• They seem to be talking about the age range 25-44. What about cases where exactly one of the people involved is outside of that range? Commented Jun 16, 2015 at 9:21

Note: On a closely related topic, most software packages agree on how to find the median from original data, but they have very different ways of finding the lower and upper quartiles. These differences become negligible with increasing sample size, but they can be confusing to students trying to reconcile hand computation, answer book values, and values from software. [In R statistical software, typing ? quantile gets you a help page that lists nine different formulas in common use to find quantiles (hence quartiles). The median is the 50th quantile, but the methods mainly agree for medians.]
