Instant and powdered coffee
In this exercise, you will analyze the prices of instant and powdered coffee in Indian markets. Grouped histograms are excellent tools for comparing different distributions side by side, mainly when simple statistical measures fall short of providing a comprehensive description of the data.
The DataFrames
package has been imported for your convenience, and the coffee
DataFrame is readily available for analysis.
