Day 3: Data Entry in SPSS – Building Your Dataset

Welcome to Day 3 of your SPSS tutorial series! Today, we’ll focus on one of the most fundamental tasks in SPSS: data entry. Whether you’re creating a dataset from scratch or preparing an imported file for analysis, learning how to efficiently input and manage your data in the Data View is essential.


Understanding the Data View

The Data View in SPSS is where you input and organize your dataset. It resembles a spreadsheet:

  • Rows represent cases (e.g., individual survey responses, participants, or records).
  • Columns represent variables (e.g., age, income, or gender).

Here’s a quick refresher: variables are defined in the Variable View, and their corresponding data is entered in the Data View.


Steps for Entering Data in SPSS

Follow these steps to enter data into SPSS:

Step 1: Create Variables

Before entering data, you must define your variables in the Variable View. For this example, let’s create three variables:

  • ID (Unique identifier for each respondent)
  • Age (Respondent's age in years)
  • Gender (Coded as 1 = Male and 2 = Female)

Refer back to Day 2 if you need a refresher on defining variables.

Step 2: Switch to Data View

  1. Once the variables are defined, switch to the Data View by clicking the corresponding tab at the bottom of the SPSS window.
  2. You’ll see the variables you created listed as column headers.

Step 3: Input Data

Start entering data into the cells, row by row. Here’s an example dataset:

ID Age Gender
1 25 1
2 32 2
3 29 1
4 40 2
  • Use Tab or Enter to quickly move to the next cell.
  • If you make a mistake, simply click the cell and re-enter the correct value.

Step 4: Save Your Dataset

  1. Go to File > Save As, and name your dataset (e.g., Day3_DataEntry.sav).
  2. Saving ensures your work is preserved for future analyses.

Tips for Efficient Data Entry

  1. Plan Your Variables First: Clearly define the variables and their properties in the Variable View before entering data.
  2. Use Value Labels: Assign labels to coded variables (e.g., 1 = Male, 2 = Female) for easier interpretation.
  3. Copy-Paste Data: If your data is in Excel, you can copy it and paste it directly into SPSS. Make sure the variable names in Excel match those in SPSS.
  4. Utilize Keyboard Shortcuts: Use Tab to move right and Shift + Tab to move left.

Dealing with Missing Data

Missing data is common in real-world datasets. Here’s how to handle it during data entry:

  • Leave the Cell Blank: This is the default method for missing values. SPSS automatically treats blank cells as missing.
  • Use a Placeholder Code: Define a specific code for missing data (e.g., -999) in the Missing column of the Variable View. This ensures missing values are excluded during analysis.

Practice Exercise

Let’s create a dataset for practice.

  1. Open a blank dataset in SPSS.

  2. Define the following variables in the Variable View:

    • ID: Numeric (Nominal)
    • Age: Numeric (Scale)
    • Gender: Numeric (Nominal, with value labels 1 = Male, 2 = Female)
    • Income: Numeric (Scale)
  3. Enter the following data in the Data View:

ID Age Gender Income
1 23 1 35000
2 28 2 40000
3 31 1 45000
4 25 2 38000
  1. Save your dataset as Day3_Practice.sav.

Common Mistakes to Avoid

  • Skipping Variable Definition: Always define variables in the Variable View first to prevent errors during data entry.
  • Mixing Data Types: Ensure numeric data is entered in numeric fields and text data in string fields.
  • Not Saving Regularly: Save your dataset frequently to avoid losing progress.

Key Takeaways

  • The Data View in SPSS is where you input and organize your dataset.
  • Proper planning of variables in the Variable View simplifies data entry.
  • Use placeholders or leave cells blank to manage missing data.
