Which of the choice of graph would you use to summarize the distribution of the following variable: Number of patients with 0, 1. 2+ vessels with >75% stenosis Histogram or Bar chart
Homework Answers
Since the variable "Number of patients with x vessels with 75% stenosis" only have three categories i.e. a person would either have 0 vessels or 1 vessel or more than 1 vessels, therefore, here bar chart is more suitable than a histogram as the variable is categorical. Below is the example of the visualization of this variable with the random numbers of the patient for each category.
