How to Create a Box Plot on StatCrunch

The StatCrunch website allows subscribers to enter and analyze data sets entered by you or other users. You can create a variety of graphs to visualize your data, including box plots. A box plot summarizes the data set by displaying the highest and lowest values, the median value and the upper and lower quartiles. Use a box plot to find outliers in your data set.
