Percent Rank dialog

Use this dialog to create a percent rank calculation. A percent rank calculation calculates the relative position of a value in a group of values, and expresses the result as a percentage. For example, you might want to find out which products are in the top 25% and top 50% of best selling products. In other words, if you calculate the percent rank for sales totals for 15 stores (highest value ranked 1):

You can therefore find the top 25% and 50% of the best performing stores.

Note: Percent Rank analysis is similar to cumulative distribution.

Rank based on

Use this drop down list to choose the item for which you want to calculate the percentage rank. For example, to calculate the percent rank of stores, you might choose Sales SUM.

Use the adjacent drop down list to specify the ranking order. For example, you might choose Highest Value Ranked 1 if you want stores with the highest sales to have the highest ranked list positions. In other words:

Then rank based on

Use this drop down list to choose an item that is used to determine the rank of values if they have tied ranks (that is, the same rank in the Rank based on field).

For example, to find stores with the highest sales and lowest costs you might choose the following:

In other words, if you have two stores with the same Sales SUM value, you might determine the rank by looking at the Costs SUM value to see which store has the lowest costs.

Restart ranking at each change in

Use this list to specify the groups to be used to arrange results into groups (sometimes referred to as partitions).

For example, to calculate a percent rank of Sales SUM values within year, you might choose Calendar Year. In other words, if Sales SUM values span two years you would have a best performing store for each year.

If you do not specify a group, Discoverer treats all worksheet values as a single group.


This read-only field displays the underlying formula that you are building as you specify values for the fields above. This formula is updated each time you change one of the values in the fields above. When you click OK, the formula is transferred to the Calculation field in the "New Calculation dialog" or the "Edit Calculation dialog".
