This makes sense, the median is the average of the middle two numbers.Ħ. Displayrs box and whisker plot maker has a range of options for you to quickly create your free online box plot. Sadly, Google Sheets doesn’t have a function to show field and whisker plots natively. It enables you to summarize essential particulars of a set of knowledge at a look.

You can verify this number by using the QUARTILE.EXC function or looking at the box and whisker plot.ĥ. How to Make a Box and Whisker Plot in Google Sheets. Generate Box and Whisker diagram easily with this free. In this example, n = 8 (number of data points).Ĥ. A box plot, also known as box & whisker plot, is a diagrammatic representation of data to illustrate median, quartiles and range of data set. This function interpolates between two values to calculate a quartile. For example, select the even number of data points below.Įxplanation: Excel uses the QUARTILE.EXC function to calculate the 1st quartile (Q 1), 2nd quartile (Q 2 or median) and 3rd quartile (Q 3). Most of the time, you can cannot easily determine the 1st quartile and 3rd quartile without performing calculations.ġ. As a result, the whiskers extend to the minimum value (2) and maximum value (34). As a result, the top whisker extends to the largest value (18) within this range.Įxplanation: all data points are between -17.5 and 34.5. Therefore, in this example, 35 is considered an outlier. A data point is considered an outlier if it exceeds a distance of 1.5 times the IQR below the 1st quartile (Q 1 - 1.5 * IQR = 2 - 1.5 * 13 = -17.5) or 1.5 times the IQR above the 3rd quartile (Q 3 + 1.5 * IQR = 15 + 1.5 * 13 = 34.5). In this example, IQR = Q 3 - Q 1 = 15 - 2 = 13. Note: After clicking 'Draw here', you can click the 'Copy to Clipboard' button (in Internet Explorer), or right-click on the graph and choose Copy. 7 Make a box by drawing horizontal lines connecting the quartiles. The mark should be a vertical line at each quartile, starting slightly above the plot line. Take the values of your first, second, and third quartiles and make a mark at those numbers on the plot line. Q 3 = 15.Įxplanation: the interquartile range (IQR) is defined as the distance between the 1st quartile and the 3rd quartile. Mark your first, second, and third quartiles on the plot line. The 3rd quartile (Q 3) is the median of the second half. The 1st quartile (Q 1) is the median of the first half. The median divides the data set into a bottom half.
The x in the box represents the mean (also 8 in this example). On the Insert tab, in the Charts group, click the Statistic Chart symbol.Įxplanation: the middle line of the box represents the median or middle number (8).
