They take up less space.В Box and whisker plots use less space when compared to other types of data graphs and charts.

If these numbers are far away from the averages, you can use dots to represent them.Д«ox and whisker plots offer the following advantages: The highest and lowest numbers in your data can sometimes be outliers. Whiskers are lines that identify numbers outside of the average results. You draw boxes to connect the first quartile to the third quartile, with the boxes representing the averages of your data. Dividing the information in this way helps you input the data onto the plot.

When you create a box and whisker plot, separate your data into quarters, called quartiles. It also helps determine outliers in your data. It takes a large amount of numbers and simplifies them into averages so data is easily understood. Related: Research Associate Resumes What is a box and whisker plot?ДЄ box and whisker plot, or box plot, is a diagram that visually displays data. In this article, we explain the purpose of box and whisker plots and the steps that you can take to create one.

Once you learn how to create box and whisker plots and how to interpret them, you may find your data to be more digestible. Box and whisker plots are one method of organizing data that makes information easier to consume. Again, you can verify this number by using the QUARTILE.EXC function or looking at the box and whisker plot.A large amount of data can be best understood through a visual representation. This makes sense, the median is the average of the middle two numbers.Д¦. You can verify this number by using the QUARTILE.EXC function or looking at the box and whisker plot.ДҐ. In this example, n = 8 (number of data points).Д¤. This function interpolates between two values to calculate a quartile. For example, select the even number of data points below.Д®xplanation: 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.ДЎ. 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.Д®xplanation: 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. Q 3 = 15.Д®xplanation: the interquartile range (IQR) is defined as the distance between the 1st quartile and the 3rd quartile. 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.Д®xplanation: the middle line of the box represents the median or middle number (8).
