First, the p-value is small (about .02 for medians, .007 for means). This means that if there really were no difference between the groups (the null model), then a result at least as extreme as the researchers found (favoring the unrestricted sleep group by that much or more) would happen in about 1-2% of random assignments by chance alone.

In this example, the first quartile is 48 and the third quartile is 54. Hence the interquartile range is 54-48 = 6. I’ll add a number to the above dataset to illustrate how to find the quartiles for an even number of values (what the heck, the data is bogus anyway):
