How to Back Code into a Binary - Grid Variable Set

Introduction

When a Binary - Grid variable set has open-ended responses there will be one Text variable for each part of the grid. For example a brand image question may have a Text variable for each brand, where the respondents have provided additional images for each. The open-ended responses can be combined with the main data from the question using Back Coding.

Method

The open-ended responses can be combined with the main data from the question using Back Coding. The process requires two things:

• The Binary - Grid variable set is first split up into a set of Binary - Multi variable sets, with one variable set corresponding to each of the Text variables containing the open-ended responses. In the brand image example this would mean one Binary - Multi variable set for each brand.
• The open-ended responses are separated Text questions and NOT combined into a Text - Multi.

Starting with a Binary - Grid variable set, the steps are as follows:

1. Make a copy of the variables from the grid by highlighting the variables in the Data Sources tree, right-clicking, and selecting Duplicate.
2. Make a new Binary - Multi variable set for the variables corresponding to each of the open-ended response variables by selecting those variables, right-click > Combine.
3. On the Object Inspector, Structure should be set to Binary - Multi.
4. Make sure that the variable labels from the new Binary - Multi variable sets are identical.
5. Highlight the Text variables for the open-ended responses in the Data Sources tree and click the Plus (+) that appears when you hover over them.
6. Select Text Categorization, and in the dialog that appears select Multiple themes then click Start.
7. Select Inputs and Back Coding.
8. For each row, select the appropriate question in the Corresponding back-coding variables section and click OK.
9. Code the responses as normal.
