1. Grouping Data in a Pivot Table can help you do what?
valentina_108 [34]

Answer:

1.Grouping data in a PivotTable can help you show a subset of data to analyze. For example, you may want to group an unwieldy list of dates or times (date and time fields in the PivotTable) into quarters and months, like this image. Note:  The time grouping feature is new in Excel 2016.

2.Select the rows or columns you wish to grouP

On the Data tab, in the Outline group, click the Group command.  

In the Group dialog box, select Rows or Columns and click OK.

3.Select the rows or columns you wish to ungroup.

On the Data tab, in the Outline group, click the Ungroup command.  

In the Group dialog box, select Rows or Columns and click OK.

4.

1.Launch Microsoft Excel.

2

Browse to and open the workbook file containing the pivot table and source data for which you need filter data.

3

Select the worksheet containing the pivot tab and make it active by clicking the appropriate tab.

4

Determine the attribute by which you want to filter data in your pivot table.  

The attribute should be one of the column labels from the source data that is populating your pivot table.

For example, assume your source data contains sales by product, month and region. You could choose any one of these attributes for your filter and have your pivot table display data for only certain products, certain months or certain regions. Changing the filter field would determine which values for that attribute are shown.

5

Force the Pivot Table Wizard or Field List to launch by clicking a cell inside the pivot table.

6

Drag and drop the column label field name you wish to apply as a filter to the "Report Filter" section of the pivot table field list.  

This field name may already be in the "Column Labels" or "Row Labels" section.

It may be in the list of all field names as an unused field.

7

Set the filter to display one of the values for the field.  

You can set the filter to display all values or only one. Click the arrow beside the filtered label and check the "Select Multiple Items" check box if you would like to select certain values for your filter.
