BOXPLOTS AND WHISKERS
Scenario:
You work for the Medical Center's retail division. This division is responsible for managing the  
sales and rentals of products from the gift shops, cafes, cafetrias, and medical equipment
rentals. You've been asked by the Director to undertake initiatives to boost sales at the gift
shops. You've worked with the Marketing Department to produce a couple of posters to
strategically place throughout the system. You're expected to create a boxplot & whiskers
diagram for each scenario (sales without posters & sales with posters).
Gift Shops Sales w/o Posters Sales w/Posters
218 215 240
224 180 220
236 150 190
252 180 175
270 201 220
282 207 215
292 195 219
304 180 295
Please provide your interpretation of the results. For example, you might want to compare the two
diagrams and point out the similarties and differences. You may want to share some relevant descriptive
statistics about the two groups of data.

Expert Solution

For better understanding I have shown the steps to find the median and quartiles and then drawn the boxplot using them

Sales w/o Posters  

Sales w/Posters

Comparing the two boxplot we see

That the sales has improved with display of poster.
The median value for sales without poster was 188.5 but with with poster it has increased to 221.75

Also without poster ther max sale was 215 but with poster it has scaled upto 295.

The min sales with poster is 175 with is considerable more than the min sales without poster.
