Box and whisker with mean and outliers Part of PowerCharts XT
A box and whisker chart is a statistical chart that is used to examine and summarize a range of data values for multiple categories of data. The chart draws a statistical conclusion for the given data using the five number summary principle. This chart is very useful to observe the mean, median, upper and lower quartiles, and deviations for a huge set of data. This chart can also showcase outliers (a data point which falls more than 1.5 times the interquartile range above the third quartile or below the first quartile). The boxes are drawn as vertical bars divided into the upper box and lower box; the size of each box is determined by the data values. Whiskers are drawn as lines extending from the boxes. This chart is commonly used for showcasing results of statistical analysis, scientific analysis, test results analysis, marketing analysis, networking data analysis, analytics and general analysis.
