# Use the Rank and Percentile Tool from the Analysis ToolPak in Excel 2007 and Excel 2010 to create ranking tables

## Introduction

Welcome to my latest hub looking into the tools available in the Analysis ToolPak which is part of both Excel 2007 and Excel 2010. In this hub, I will be investigating the **Rank and Percentile** Tool.

**Ranking** allows you to rank all your data in order from highest to lowest and **Percentile** allows you to easily categorise your data into percentiles such as the top 25%, top 50% etc.

To illustrate how to use this tool, I will work through an example. In my example, I have a class of 30 students. I have just got their latest results and want to rank them and assign them grades based on their ranking within the class. The top 10% get an A, the next 20% get a B, the next 20% get a C and the remainder get a D grade.

My ultimate goal is to end up with a table such as the one shown below with as little manual work as possible:

In conjunction with the **Rank and Percentile** tool, I will use the **MATCH** and **INDEX** functions to assign the student names to the raw data created by the tool. I will then use the **IF** function to automatically assign a grade to them based on their result as well.

## Adding the Analysis ToolPak in Excel 2007 and Excel 2010

Before using the tool, we need to ensure that the Analysis ToolPak is present in Excel. The ToolPak can be found on the **Data** tab, in the **Analysis** group and is accessed via the **Data Analysis** button. I have a hub that covers adding both the **Developer** tab and the Analysis ToolPak to both Excel 2007 and Excel 2010 which can be found here:

## Using the Rank and Percentile Tool in Excel 2007 and Excel 2010

Now that we have added the Analysis ToolPak, select the **Data Analysis** button and select **Rank and Percentile** as shown below.

The tool itself it quite straightforward and easy to use:

- First select the
**Input Range** - If your data is in columns, leave
**Grouped By**as**Columns**(otherwise select**Rows**) - If you have labels for your columns, then select
**Labels in first row** - Lastly, select your
**Output options**, select**Output Range**to place it in a specific place on your worksheet or select**New Worksheet Ply**or**New Workbook**depending on your preference (we placed the tool’s results next to the original data in the example we are working through today) - Click
**OK**and Excel will create your Rank and Percentile table

You can see the output above from the tool. Excel has ranked every student and given them their exact percentile (the Percent column), however, rather than using the students names, there is a column called **Point**, which is the row number of each student. To turn the **Point** column into a column containing the student’s name, I need to turn to the **MATCH** and **INDEX** function.

## Using the MATCH and INDEX function in Excel 2007 and Excel 2010 to convert the results in the Point Column created by the Rank and Percentile Tool to the actual

These two functions work in tandem to convert the results in the Point column to the student’s name.

First:

- The
**MATCH**function looks for the number in the Point column and then finds its exact match in the column labelled Student No. **INDEX**then looks for the cell adjacent to the result that**MATCH**found and returns the student’s name.

In the figure below, you can see the formula that turns 12 in the Point column to our top student (Ed Bradley)

The entire formula is

=INDEX($B$3:$B$32,MATCH(F5,$A$3:$A$32))

It is easier to understand broken down into its component parts, **MATCH** and **INDEX**

- The
**MATCH**function looks for the contents of F5 (12) in the range A3 to A32

MATCH(F5,$A$3:$A$32))

- The
**INDEX**function then looks in the range B3 to B32 for the cell adjacent to the cell found by MATCH

So, **MATCH** finds 12 in cell A14 and **INDEX** finds Ed Bradley in the cell adjacent to A14

**Note:** *the $’s added to the cell references tells Excel 2007 and Excel 2010 that these cell references do not change even when the formula is copied to other cells (known as absolute cell references). This prevents Excel from adding one to each cell reference each time you copy it (the formula would become =INDEX(B4:B33,MATCH(F4,A4:A33)) rather than =INDEX($B$3:$B$32,MATCH(F4,$A$3:$A$32)) which may otherwise provide a potentially incorrect result).*

I placed this formula in the column to the right of the Point column to make it easier to complete our final table with the column header of Student.

I have a hub that looks at both the **MATCH** and **INDEX** functions in far more detail, this time to create Top Ten lists which can be found here:

## Completing our table ranking our students in Excel 2007 and Excel 2010

Now that we have a column containing our students names, to complete the table:

- Hide the
**Point**and**Rank**columns (do not delete them or the formulas will break) - Copy the
**Percent**column and place it to the right of the original column - Change the name of the original
**Percent**column to**Grade**

Remember that we wanted to do this as automatically as possible. To assign our students a grade, we will use an **IF** statement as shown below:

=IF(K3<50%, "D", IF(K3>90%, "A", IF(K3>70%,"B", IF(K3>50%, "C"))))

This formula looks at the Percent column and looks at the percent and then assigns a letter based on the result it finds.

**Note:** *The order is vitally important, if we did it in the order C, B, A then we would end up with only D and C grades as Excel would look at all numbers above 50% and give them a C and the formula would end.*

- Copy this formula to the remainder of the
**Grade**column.

Now we have our completed table, which looks like the figure below:

## Conclusion

The **Rank and Percentile** Tool from the Analysis ToolPak which is available in Excel 2007 and Excel 2010 allows us to work with data and rank it and then have Excel calculate its percentile.

In my example today, I took my (fictional) class of students and ranked them according to their test results. I then gave them a grade depending on where they sat ranked against their peers.

To accomplish this, I not only used the Rank and Percentile Tool, I also used the **MATCH** and **INDEX** functions to convert the results so that the name of the student appeared next to their grade, and then also used the **IF** command to automatically assign them their grade.

This hub is part of a series of hubs investigating the tools available in the Analysis ToolPak. The other tools I have looked at in greater depth include:

**Histogram**: this tool allows us to look at the distribution of your data in graphical form. You can configure the boundary values the histogram uses to, for example, look at student exam data and chart the grade distribution across their results.

**Moving Average** allows you to analyse your data for trends and chart your data and any trend line created by the tool should a trend be present. In my hub on this tool, I looked at my historic web traffic and whether there was a trend in that data.

**Sampling** creates a random sample from a larger population you can analyse. I created lottery numbers from a pool in my example.

**Regression** and **Correlation** allow you to look at the relationship between variables. **Correlation **allows you to test the relationship between variables and **Regression** allows you to visually display this using a linear regression. In the hub on correlation, I investigate the relationship between daily temperatures and pie sales and in the hub on regression, fish mortality and Phosphate and Nitrogen concentrations in water.

I do hope that you have found this hub both useful and informational. If you have any comments, please feel free to leave them below.
