I rarely use box-and-whisker plots and histograms in the day-to-day of my job but I have encountered them in presentations of clinical trial data. These data presentations are normally developed by other members of my team so I have not yet had experience in creating one other than in this course.
I do find them easy to understand and especially beneficial to show the statistical results of a clinical trial rather than solely reading a statistical analysis. Having a visual representation of the distribution of the data certainly makes it much easier to draw conclusions and present these conclusions to others who are not specifically involved in the clinical trial.
