SPSS 5.0|Importing External Data

Zhenting HE / 2023-12-22

1. SPSS’s Main Interface #

(1) SPSS has two primary windows: #

  • Data Editor (Data View): Where you input and view the dataset. You can work with variables and cases in this window.
  • Output Viewer: Displays the results of your analyses, including tables, charts, and statistical tests. It stores output in a .spv file format.

(2) Two main windows and file formats: #

  • Data Editor (Data View): .sav file (SPSS dataset format)
  • Output Viewer: .spv file (SPSS output format)

(3) Third Window: Syntax Editor #

  • This is used for writing and executing SPSS commands or syntax scripts, saved as .sps files.

(4) SPSS can import or open common data formats: #

  • SPSS .sav files
  • Excel .xls or .xlsx files
  • CSV (Comma-separated values) files
  • Other types like tab-delimited files or even text files

(5) Each window allows you to run data processing and analysis through menus. #

2. Importing External Data #

When you import external data (like Excel, CSV, etc.) into SPSS, consider the following:

(1) Does the first row contain variable names? #

  • SPSS often needs to know if the first row of your data file contains the names of the variables. If it does, ensure you select the “Read variable names from the first row of data” option when importing.

(2) Does the data contain multiple sheets (Xls, Xlsx, CSV)? #

  • In Excel files, you might have multiple sheets. SPSS allows you to choose which sheet to import.

(3) Does the data require a Variable View adjustment? #

  • After importing data, check the Variable View to define variable names, labels, value labels, measurement levels, and other characteristics. This is important if SPSS didn’t recognize them automatically.

3. Importing External Data - Practical Operation #

Let’s take an example of an education dataset, for instance, a survey of students’ performance in different subjects. Here’s how to import it into SPSS:

Example Data (Excel file or CSV): #

Student ID Name Math English Science GPA
101 Alice 88 92 85 3.9
102 Bob 75 78 70 3.2
103 Charlie 95 89 90 4.0
104 Diana 82 84 88 3.7

You can save this as an Excel file (e.g., student_performance.xlsx).

Step-by-Step Import Process: #

  1. Open SPSS: Launch SPSS and make sure you are in the Data View window.

  2. Go to File > Open > Data: In the menu bar, go to File > Open > Data. A file explorer will appear.

  3. Choose Your File Type: In the file explorer, change the file type filter to the appropriate type (e.g., .xls, .xlsx, or .csv).

  4. Select Your File: Find and select the education dataset you saved (student_performance.xlsx), then click Open.

  5. Set Import Options: SPSS will show an import dialog box.

    • Ensure the first row of your Excel sheet contains variable names (e.g., Student ID, Name, Math, etc.).
    • If your Excel file has multiple sheets, choose the correct sheet you wish to import (e.g., “Sheet1”).
    • Click OK to import the data.

  6. Check the Imported Data: After importing, you’ll see the data in the Data View window. Check that the variable names appear correctly in the columns, and the data matches your expectations.

  7. Adjust Variable View: Switch to the Variable View to adjust:

    • Variable names: Ensure they are short, descriptive, and free of spaces (e.g., change Student ID to Student_ID).
    • Variable labels: Add labels if necessary for better understanding (e.g., Student_ID = “Unique identifier for each student”).
    • Value labels: If you have categorical data (e.g., grades), define value labels (e.g., Math = “A” = 90-100, “B” = 80-89, etc.).
    • Measurement levels: Set the measurement level (Nominal, Ordinal, Scale) for each variable as needed (e.g., GPA would be Scale, while Name would be Nominal).

  8. Save the Data: After confirming everything is correct, save the dataset by going to File > Save As and choosing .sav format to save it as an SPSS dataset.

Summary #

By following these steps, you can easily import external data (like Excel or CSV files) into SPSS for analysis. Ensure that you review and adjust the Variable View after importing to make sure the data is correctly structured for analysis.
