This free online software (calculator) computes notched boxplots for every variable (=column) of the multivariate dataset. A notch is drawn in each side of the boxes.

If the notches of two plots do not overlap this is strong evidence that the two medians differ (Chambers et al., 1983, p. 62).

Enter (or paste) a matrix (table) containing all data (time) series. Every column represents a different variable and must be delimited by a space or Tab. Every row represents a period in time (or category) and must be delimited by hard returns. The easiest way to enter data is to copy and paste a block of spreadsheet cells. Please, do not use commas or spaces to seperate groups of digits!
