Binary Variable Generator

Create a dummy or indicator variable

Binary variables are also commonly called dummy variables or indicator variables. They are frequently used in statistical analysis, survey research, regression models, reporting and data preparation.

For example, you could create an adult variable where age 18 or above receives 1 and age below 18 receives 0.

Similar to creating a binary variable in SPSS

Statistical packages such as SPSS allow users to create or recode variables based on logical conditions. This online tool follows the same general idea: define the condition, choose the output values and create a new variable without replacing your original data.

The tool is not SPSS itself, but it can help perform common binary-variable creation tasks without statistical software.

How to create a binary variable

1. Upload a CSV, XLSX or XLS file, or paste CSV data.
2. Select the worksheet if you are using an Excel workbook.
3. Click Load Variables.
4. Enter a name for the new variable.
5. Choose the value to assign when the condition is true and the value to assign when it is false.
6. Select a source variable, comparison operator and comparison value.
7. Add additional conditions if needed.
8. Choose AND or OR when using multiple conditions.
9. Click Create Binary Variable.
10. Download the resulting CSV or Excel dataset.

Binary variable example

Suppose your data contains:

name,age,city
Ali,22,Islamabad
Sara,17,Lahore
David,42,Islamabad
Ayesha,31,Karachi

You could define:

New variable: adult
Condition: age >= 18
True value: 1
False value: 0

The result becomes:

name,age,city,adult
Ali,22,Islamabad,1
Sara,17,Lahore,0
David,42,Islamabad,1
Ayesha,31,Karachi,1

Use multiple conditions with AND

AND means every condition must be true. For example:

age >= 18
AND
city = Islamabad

A record receives the true value only when both conditions are satisfied.

Use multiple conditions with OR

OR means at least one condition must be true. For example:

city = Islamabad
OR
city = Lahore

Records from either Islamabad or Lahore receive the true value.

Supported conditions

Choose your own binary values

Binary variables do not have to use only 1 and 0. You can specify your own values, such as Yes and No, Eligible and Not Eligible, Present and Absent, or any other two-category coding scheme.

Original variables are preserved

The generator does not overwrite the variables used in your conditions. The newly created binary variable is appended as the last column of the dataset.

CSV and Excel support

You can create binary variables from CSV, XLSX and XLS files. Excel workbooks with multiple worksheets can be opened by selecting the worksheet containing the data you want to process.

Common uses for binary variables

Binary variables are commonly used in survey analysis, regression modelling, demographic research, monitoring and evaluation, health research, eligibility rules, customer segmentation, reporting and many other analytical workflows.

Is my data uploaded?

No. Your CSV or Excel dataset is processed locally in your browser. The file does not need to be uploaded to MK Tech Tools for variable creation.
