 function stands for rounding up to the nearest integer, so e.g. <span class="math inline">\(\text{ceiling}(2.1) = 3\)</span>. To compute the inter-quartile range for total goals scored, we compute the needed ordinal ranks as
<span class="math display">\[\text{rank}(25) = \text{ceiling}\left(\frac{25}{100} \times 32 \right) = 8\]</span>
which means we can take the 8th value in the ordered list as the 25th percentile, which equals 2, and
<span class="math display">\[\text{rank}(75) = \text{ceiling}\left(\fr
