What are the median and the quartiles of a data-set?

  • The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
  • The first quartile is the median of the first half of the data-set.
  • The third quartile is the median of the second half of the data-set.
  • The interquartile range is the difference of the third and the first quartile.

From this box plot, we have that:

  • The first quartile is of 39.
  • The third quaritle is of 61.

Then the IQR is:

61 - 39 = 22.
