    • Adjust decimals as needed (especially for scale variables).
    • Right-justify numeric variables for better readability.

Tips

  • Use descriptive variable names and labels for clarity.
  • Understand the different scales of measurement (nominal, ordinal, scale) to choose the appropriate statistical tests later.
  • Right-justifying numeric data improves readability.

Common Mistakes to Avoid

1. Incorrect Variable Type Selection

Reason: Using the wrong variable type (e.g., treating continuous data as categorical or vice versa) can lead to inaccurate analyses and misleading results. SPSS might not be able to perform certain operations or might produce nonsensical outputs.
Solution: Double-check your variable types in the Variable View and ensure they accurately reflect the nature of your data.

2. Ignoring Missing Data

Reason: Failing to address missing values properly can bias your results and lead to incorrect conclusions. Simply ignoring missing data can lead to a smaller sample size and skewed analysis.
Solution: Employ appropriate missing data handling techniques, such as listwise deletion, pairwise deletion, or imputation, based on the nature and extent of missing data.
