A box plot requires the minimum, maximum, median, and first and third quartiles to be drawn accurately. The median represents the middle value of the data, the first quartile indicates the value below which 25% of the data falls, and the third quartile indicates the value below which 75% of the data falls. Together, these five statistics provide a good representation of the spread and distribution of the data. Mean and standard deviation are not needed for a box plot.
