What is the average amount of giving and the average number of years of giving for corporations, foundations, and volunteers? Features: AutoSum (and outline). Instructions: Return to Sheet 1, click on any cell containing data and select Data and Sort, and sort by column A, Donor Type. To automatically insert subtotals, select Data, Outline, Subtotal, and check off the years of giving and giving columns, and uncheck other columns. You can see the averages for each donor type by selecting Use Function: Average (above the column checkboxes.) To view subtotals only (which is essentially an outline of your data), you can click on the small 2 in the upper left corner of your spreadsheet. To expand a particular section of your outline, such as volunteers, click on the + sign next to that subcategory. To return to the outline view, click on the - sign next to the subtotal for that category. Return to level 2 outline view. Modify the spreadsheet so that your data will print on a single page. Save the file as 301AutoSum. Copy your spreadsheet showing only the data that answers the question. Return to the original data by selecting Data, Subtotals, Remove All.
