5-Number Summary A 5-Number Summary is composed of the minimum, the lower quartile (Q1), the median (Q2), the upper quartile (Q3), and the maximum. These numbers discuss the spread of the data and divide the data into 4 equal parts.

Box Plot From a five-number summary, I can create a box plot on a graph with a scale. Minimum – left whisker Lower Quartile – left side of box Median – middle of box Upper Quartile – right of box Maximum – right whisker Each portion of the box plot represents 25% of the data.
