Creating a Box Plot

The box plot feature is useful to visualize the distribution summary of a variable. The box plot can also be exported as an image file and saved to the local drive.

The box plot displays differently for a variable with time variation. Each time instance will have a box plot, and all of the box plots for all time slices shall be displayed in the same visualization.

Note that it is important to manually save any time dependent information of the box plot when exporting the image file.

Summary Statistics

The Box plot displays summary statistics when the visualization is created:

  1. Count is the total number of observations in the dataset of a variable
  2. The minimum and maximum values describe the limits of the variable in question
  3. The mean describes the variable average
  4. The median is the middle value of the variable string when its values are listed in numerical order, from least to greatest
  5. The interquartile range calculates the distance between the 25th percentile and 75th percentile of the data range, offering a measure of the dispersion of the variable while ignoring extreme values
