#HOW TO READ A BOX AND WHISKER PLOT INSTALL#

To obtain Conda, it is easiest to install one of two distributions: Anaconda, a powerful Python and R distribution that includes over 250 packages for various uses, or Miniconda, a minimal version Anaconda that includes only conda, Python, package dependencies, and a few other useful packages (JupyterLab not included).

Note: The online trial of JupyterLab is a good place to start if you want to experiment with programming in Python, but for continued use in the future, it is recommended to install the Conda package and environment management system, and JupyterLab locally on your system. If your session has expired, start a new one from, and use the interface to upload your saved notebook to continue where you left off.

Make sure to download and save your notebooks locally before leaving the computer.

Take note that this JupyterLab session is hosted on and it will timeout after ~15 minutes if inactive. Try refreshing the window if loading stalls. A cloud-hosted ready-to-use online JupyterLab environment will be activated after a short wait. To try a notebook online, just open and click Try JupyterLab. We will be using JupyterLab, a modern web-based notebook interface for Python, that requires no installation on the user’s part.

#HOW TO READ A BOX AND WHISKER PLOT CODE#

Sharing small code projects (such as visualizations!) generally becomes much simpler with the notebook approach, since you can save the entire notebook and send it to others. This makes working with code and experimenting with changing parameters much more flexible and is particularly suitable for interactive data exploration, where the Python programming language shines. In a notebook, on the other hand, the code is broken down into cells, which can be run one at a time, displaying results right in the editor. The traditional way of programming would be to write some code in a text file, then building and running it to generate an output. There are different norms in place for the box-and-whisker plot in different disciplines though for example, the length of the whiskers can denote the entire range in data, the standard deviation, the midpoints of the first and fourth quartiles, or a certain interval in which some percentage of the observations fall. The whiskers in turn are drawn based on the largest and smallest values falling within 1.5 times the interquartile range beyond the first or third quartile, and any outlier values are usually marked using small extraneous symbols above or below the whiskers.

In the most common variant of the box-and-whisker plot-often called Tukey’s plot-the box is based on the size of the interquartile range-that is to say, the range around the median including half of all observations. The visualization is composed of parallel rectangular shapes arranged over the x-axis by category, with lines extending along the y-axis to denote the extent of variation in the data. This is usually accomplished by plotting the medians in observed values, as well as the overall range in variation around the median. Box-and-whisker plots are a visualization type commonly used in scientific publications to show quantitative variation across categorical variables within the collected dataset.
