Soap sales by packaging type over a 5 week study
A data frame with 5 observations on the following 3 variables.
number of box packages sold
number of foil packages sold
number of shrink wrapped packages sold
An in-store study was run to test consumer preference of packaging for a soap. The study was run for 5 weeks with the number of packages sold each week recorded. Note, after the third week there was a supply disruption so there were no boxed soaps available for sale.
