About the Five-Number Summary Calculator

The five-number summary condenses a dataset into five key values that describe its center and spread: the minimum, the first quartile (Q1), the median, the third quartile (Q3), and the maximum.

Formula: Min and Max are the smallest and largest values · Median is the middle value of the sorted data · Q1 and Q3 are the medians of the lower and upper halves

These five values are exactly what's needed to draw a box plot, making this summary a fast way to visualize a dataset's range, central tendency and skew at a glance.
