Final answer:
Using a bar chart in data visualization tools, group smokers by their PCPs to display the number of patients per provider as categorical data.
Step-by-step explanation:
To group a population of smokers with PCP's (Primary Care Providers) in your clinic by different PCPs with one bar per provider, you would use a bar chart. This chart type is suitable for displaying and comparing categorical data. First, ensure you have the data for each smoker's PCP.
Then, using data visualization software or tools available in SlicerDicer, input your data appropriately to generate the bar chart. Each bar in the chart would represent a different PCP and the number of patients associated with that provider.
