Final answer:
To insert subtotals in a spreadsheet, sort the data by the Level field, use the Subtotals feature to sum the Weeks Completed field for each category, and add a grand total for all categories.
Step-by-step explanation:
The student is seeking assistance with using spreadsheet functions, specifically to insert subtotals for each category in the Level field. To do this using a Sum function:
- First, sort the data by the Level field from Largest to Smallest.
- Then, use the Subtotals feature (usually found in the Data menu) to add the values in the Weeks Completed field for each Level category.
- Finally, insert a grand total at the end of the data range to sum up all the values of Weeks Completed.
The result will be a dataset organized by Level, with each category’s total Weeks Completed displayed, and a grand total representing the sum of Weeks Completed for all categories.
