Exercise

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.

Instructions

100 XP
  • Import the StatsPlots package
  • Create a grouped histogram using the Retail Price column from the coffee DataFrame.
  • Group the histogram by the Variety column
  • Select sandybrown and brown for the colors in that specific order.
