SPSS can support a transparent quantitative workflow when data are prepared carefully and every test is chosen for a substantive reason. The steps below provide a practical starting framework. Always follow your supervisor’s directions, institutional requirements and the standards relevant to your research design.
Build a clean dataset
Define variable names, labels, values, missing-value codes and measurement levels before running procedures. Examine impossible values, duplicate entries and reverse-coded items. Save an untouched original dataset and a separate working copy.
Explore the data first
Use frequency tables, summary statistics and suitable plots to understand distributions and identify anomalies. Record sample sizes for each analysis. Missingness patterns matter: a test run on fewer cases can answer a different question than the full dataset suggests.
Choose the test from the design
For comparing two independent groups, consider an independent-samples test when assumptions support it; paired observations require a paired approach. Several groups may call for ANOVA or appropriate alternatives. Regression is suited to certain predictive or explanatory questions, but the design and assumptions determine its meaning.
Interpret beyond a p-value
Report estimates, uncertainty or confidence intervals and effect sizes when applicable. Explain what the result means in the field rather than copying output tables. Preserve syntax or an analysis log so another researcher can reproduce the chosen procedures.
Questions to discuss with your guide
- Were missing-value codes interpreted correctly?
- Are samples independent or paired?
- What does the reported effect mean practically?
The takeaway
SPSS can support a transparent quantitative workflow when data are prepared carefully and every test is chosen for a substantive reason. For project-specific decisions, seek qualified supervisory or specialist input and document the basis for your choices.
