Iqr of boxplot
WebThe IQR is used to build box plots, simple graphical representations of a probability distribution . The IQR is used in businesses as a marker for their income rates. For a symmetric distribution (where the median equals the midhinge, the average of the first and third quartiles), half the IQR equals the median absolute deviation (MAD). Webtherefore represents the interquartile range (IQR). The arithmetic mean of the group of data is plotted with a symbol, in this example a plus sign is used. The schematic style of box-and-whisker plot is shown in Figure 3. This also draws the box height as the interquartile range, and plots a symbol at the arithmetic mean.
