# Recoding Variables in SPSS Statistics

## Introduction

The instructions below will show you how to recode variables. You can use recoding to produce different values or codes for a variable. Recoding can be done in one of two ways:

• Recoding into the same variable
• Recoding into a different variable

In this guide, we will concentrate on recoding into a different variable, for which there are 3 main types of recoding:

• Recode single values
• Recode a given range of values
• Recode data into two categories

We will use an example of each type in order to demonstrate how to recode variables in SPSS Statistics.

## Recode single values in SPSS Statistics

Example: The data given below represents runs scored by 5 batsmen in a national-level match. Recode the data so that the batsmen are rank ordered by their number of runs, with the batsman with the highest runs given a code of "1" and the batsman with the lowest runs given a "5".

 Number of runs by batsmen Batsmen 1 2 3 4 5 Runs 86 120 56 10 18
• Enter the data in the SPSS Statistics Data Editor and name the variable "Runs".

Remember that each individual's results go on a separate line (row) in SPSS Statistics.

• You need to highlight the Runs variable in the left-hand box by clicking on it and then click the button to move it across to the Numeric Variable -> Output Variable: box.

• In the -Output Variable- area show below, give the new variable you are about to create a name and label. In this example, we have named the new variable "Ranked-Runs" and the label as "Ranked Runs" (see the ).

• Click the button.

• You should now see that the Numeric Variable -> Output Variable: box has now changed to reflect these changes (see the ).

• Click the button.

• Enter the first score (120) into the Value: box within the -Old Value- area, and set the new code of "1" into Value: box within the -New Value- area.

• Click the button.

• Repeat for all other values, such that you are presented with the following screen:

• You will have returned to the previous screen and will now have to click the button. This will take you to the Data View Editor, which will now show that you have created a new variable that is based on recoding your existing variable:
