1. Purpose  This assignment illustrates how data analytics can be used to create strategies for sustainable organizational success while integrating the organization’s mission with societal values. You’ll apply statistical time series modeling techniques to identify patterns and develop time-dependent demand models. You’ll practice organizing and delivering a presentation to senior decision-makers. The PowerPoint presentation includes an audio component in addition to speaker notes.   Resources: Microsoft Excel®, DAT565_v3_Wk6_Data_File Scenario: A city’s administration isn’t driven by the goal of maximizing revenues or profits but instead looks at improving the quality of life of its residents. Many American cities are confronted with high traffic and congestion. Finding parking spaces, whether in the street or a parking lot, can be time consuming and contribute to congestion. Some cities have rolled out data-driven parking space management to reduce congestion and make traffic more fluid.  You’re a data analyst working for a mid-size city that has anticipated significant increments in population and car traffic. The city is evaluating whether it makes sense to invest in infrastructure to count and report the number of parking spaces available at the different parking lots downtown. This data would be collected and processed in real-time, feeding an app that motorists can access to find parking space availability in different parking lots throughout the city.  Instructions: Work with the provided Excel database. This database has the following columns: 

  • LotCode: A unique code that identifies the      parking lot
  • LotCapacity: A number with the respective      parking lot capacity
  • LotOccupancy: A number with the current number      of cars in the parking lot
  • TimeStamp: A day/time combination indicating the      moment when occupancy was measured
  • Day: The day of the week corresponding to the      TimeStamp
  • Insert a new column, OccupancyRate, recording      occupancy rate as a percentage with one decimal. For instance, if the      current LotOccupancy is 61 and LotCapacity is 577, then the OccupancyRate      would be reported as 10.6 (or 10.6%).
  • Using the OccupancyRate 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 OccupancyRate and LotCode      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      as catter plot showing occupancy rate against TimeStamp for the week      11/20/2016 –11/26/2016. Are occupancy rates time dependent? If so, which      times seem to experience highest occupancy rates? Is this what you      expected?
  • Presentation:  Create a 10- to 12-slide      presentation with speaker notes and audio. Your audience is the City      Council members who are responsible for deciding whether the city      invests in resources to set in motion the smart parking space app.       Complete the following in your presentation:  
  • Outline the rationale and goals of the      project. 
  • Utilize boxplots showing the occupancy      rates for each day of the week. Include your interpretation of results.
  • Utilize box plots showing the occupancy rates      for each parking lot. Include your interpretation of results.
  • Provide scatter plots showing occupancy      rate against time of day of your selected four parking lots. Include your      interpretation of results. 
  • Make a      recommendation about continuing with the implementation of this      project.
