Assignment - 1
In this assignment, you will be following the scenario of a recently hired Junior Data Analyst in a local government office, who has been tasked with sorting and analyzing fleet inventory data that was previously imported and cleaned. You plan to use pivot tables to analyze the data in preparation for the results to be visualized in a dashboard and added to a data findings report later.
Format the data as a table: Use the Format as Table option to format the data as a table.
Use AutoSum to calculate values: Use AutoSum to find the following values for column 'C' and record each of the values:
Create a Pivot Table: Use the PivotTable feature to create a pivot table that displays the Department field in the Rows section, and the Equipment Count in the Values section, so that the pivot table displays the sum of equipment count by department.
Sort the pivot table data: Use the Sort By Value setting on the pivot table to sort it in descending order by the sum of equipment count.
Make two more pivot tables exactly the same as task 3: Follow the same steps you performed in Tasks 3 and 4 to create two more identical pivot tables so that you end up with 3 worksheets that contain identical pivot tables.
Analyze data in the pivot table: Use the PivotTable Fields pane to manipulate and analyze data in the two copied pivot table as follows:
In pivot table 2, i Collapsed all fields except the top one - Transportation.
In pivot table 3, i Collapsed all fields except the top one - CUV.
