Week 6
Instructions: Work with the provided Excel database. This database has the following columns:
Lot Code: A unique code that identifies the parking lot
Lot Capacity: A number with the respective parking lot capacity
Lot Occupancy: A number with the current number of cars in the parking lot
Time Stamp: A day/time combination indicating the moment when occupancy was measured
Day: The day of the week corresponding to the Time Stamp
Insert a new column, Occupancy Rate, recording occupancy rate as a percentage with one decimal. For instance, if the current Lot Occupancy is 61 and Lot Capacity is 577, then the Occupancy Rate would be reported as 10.6 (or 10.6%).
Using the Occupancy Rate and Day columns, construct box plots for each day of the week. You can use Insert > Insert Statistic Chart >Box and Whisker for this purpose. Is the median occupancy rate approximately the same throughout the week? If not, which days have lower median occupancy rates? Which days have higher median occupancy rates? Is this what you expected?
Using the Occupancy Rate and Lot Code columns, construct box plots for each parking lot. You can use Insert > Insert Statistic Chart >Box and Whisker for this purpose. Do all parking lots experience approximately equal occupancy rates? Are some parking lots more frequented than others? Is this what you expected?
Select any 2 parking lots. For each one, prepare a scatter plot showing the occupancy rate against Time Stamp for the week 11/20/2016 –11/26/2016. Are occupancy rates time-dependent? If so, which times seem to experience the highest occupancy rates? Is this what you expected?
