A boxplot is a graph summarizing the distribution of a set of data values. The upper and lower ends of the center box indicate the 75th and 25th percentiles of the data, the center box indicates the median and the center “+” indicates the mean. Suspected outliers appear in a boxplot as individual points “O” or “X” outside the box. The “O” outlier values are known as outside values, and the “x” outlier values are known as outside values.
