  • Before you create a PivotTable, you need to ensure that you have nice clean data with
  • Converting your data into a Table before creating a PivotTable is a good idea because:
  • When in PivotTable Fields, if you tick a field that contains numeric data, it will automatically populate which quadrant?
  • When in PivotTable Fields, if you tick a field that contains non-numeric data, it will automatically populate which quadrant?
  • To change the calculation within your PivotTable, you get more options by right-clicking one of the values, compared to customizing the calculation in the Values quadrant.
  • Rather than seeing discrete values, if you want to see percentages instead, you should go to
  • Choosing the option Rank Smallest to Largest will result in the PivotTable being sorted and displayed from smallest to largest values.
  • When does Excel automatically give you sub-totals for your PivotTable?
  • You can choose to display a sub-total as a sum and as an average, and both these items will appear separately at the bottom of the respective section in your PivotTable.
  • If you have full dates and you create a PivotTable, Excel will group these dates, such as grouping by month. You can remove this by choosing Ungroup.
  • Which of the following buttons would we need to click to group the dates below?
  • Which of the following buttons would we need to click to group a few rows from our PivotTable?
  • What would moving the Europe cell to elsewhere in the PivotTable do?
  • Which of these are correct statements about custom lists in Excel?
  • One way to filter which columns and which rows appear in your PivotTable is to use the drop-down menu that appears next to Row Labels and Column Labels.
  • To clear a filter in a PivotTable, you could:
  • The main difference between Label Filters and Value Filters is that Label Filters are for filtering based on text.
  • If you want to filter by a field that you do not necessarily want to show in the PivotTable itself, you should move this field to which quadrant?
  • If you choose Show Report Filter Pages after having selected multiple items in a filter, what would happen?
  • A PivotTable currently occupies some of Columns A and B as per the screenshot. The formula that is displayed is typed into cell D4. What would happen to the result of the formula if the filters of the PivotTable were modified?
