Scenario
You have recently been hired as an Emergency Services Analyst for the city of Lincolnton, NC. In this role, you are to analyze all emergency services incident patterns, collect statistics, prepare and disseminate information, and assist with special projects. Recently, you have been tasked with conducting analysis on the emergency services data from 911 related calls from around the city.
Part 1: You receive the email from your Director of Emergency Services, including an Excel file of source data, and are asked to analyze the calls from around the community. You will perform your analysis (in the same Excel spreadsheet) and provide an explanation in an email response (Word document). Download the source data file below.
Emergency Call Center Data File
Within the spreadsheet, perform the following:
A. Prepare a dataset from the “Source Data” spreadsheet. Remove any potential errors or outliers, duplicate records, or data that are not necessary. Provide a clean copy of the data in your email response. Copy and paste the Source Date in your Excel Spreadsheet and label the sheet, “Source Data”. Copy and paste the Clean Data Sheet in your Excel Spreadsheet and label it, “Clean Data Sheet”.
B. Explain why you removed each column and row from the “Source Data” spreadsheet or why you imputed data in empty fields as you prepared the data for analysis.
C. Create data sheets using your cleaned dataset and provide each of the following to represent the requested aggregated data.
a. Table: date and number of events OR
b. Bar graph: date and number of events
c. Label this table or bar graph in your Excel Spreadsheet, “Data and Events”
a. Table: number of incident occurrences by event type OR
b. Bar graph: number of incident occurrences by event type
c. Label this table or bar graph in your Excel Spreadsheet, “Event Type”
a. Table: sectors and number of events OR
b. Bar graph: sectors and number of events
c. Label this table or bar graph in your Excel Spreadsheet, “Number of Events”
D. Summarize your observations from reviewing the datasheets you have created and include it as part of your introduction to your analysis report analysis in Part 2. Copy and paste your Excel spreadsheets in your Part II Word document (Analysis Report) and write your observations on each chart.
Part 2: Further, the state has offered an additional funding incentive for police departments that are able to meet the standard of having a minimum of 2.5 officers onsite per incident. The Director has delegated the task to you to analyze the police department’s data to determine if the department will be eligible for additional funding. You will use the same source data provided in the Excel spreadsheet. In a Word document, complete the following questions and include the summary from Part 1 in an analysis report.
E. Create a table that shows the average number of officers assigned to each sector. Also show the total number of incidents and total number of officers and compute the overall average. Put this table in your Excel Spreadsheet and label it “Avg Officers”. Copy and paste the table you created in your Analysis Report and incorporate your comments on it.
F. Describe the fit of the linear regression line to the data, providing graphical representations or tables as evidence to support your description. Display your linear regression line in your Excel Spreadsheet and label it “Linear Regression”. Copy and paste the graph you created in your Analysis report and incorporate your comments on it.
G. Describe the impact of the outliers on the regression model, providing graphical representations or tables as evidence to support your description. This should show on your “Linear Regression” Excel Spreadsheet. Copy and paste the graph you created in your Analysis report and incorporate your comments on it.
H. Create a residual plot and explain how to improve the linear regression model based on your interpretation of the plot. Create the Residual Plot and display it in your Excel Spreadsheet. Label the sheet, “Residual Plot”. Copy and paste the graph you created in your Analysis report and incorporate your comments on it.
I. Conduct a comparative matrix for the sectors. Explain how your findings impact the operations of the police department. Create your comparative matrix in your Excel spreadsheet and label the sheet as “Comparative Matrix”. Copy and paste the table you created in your Analysis report and incorporate your comments on it.
J. Describe the precautions or behaviors that should be exercised when working with and communicating about the sensitive data in this scenario.
K. Discuss any additional tools or technologies that could impact the data collection, storage, or analysis for future projects.
L. Provide attribution for credible sources needed in completing your report.
