SPSS (Statistical Package for the Social Sciences) is used in almost every UK university psychology, business, and social science programme. Yet most students find it overwhelming the first time they open it. This guide will demystify SPSS from data entry to final write-up.
What Is SPSS and Why Do UK Universities Use It?
SPSS is a statistical analysis software package owned by IBM. UK universities use it because it can handle large datasets and perform a wide range of statistical tests without requiring you to write code. It is the industry standard in psychology, sociology, business research, and health sciences.
Setting Up Your Data in SPSS
Before running any analysis, your data must be correctly structured. This is where most students go wrong.
Variable View vs Data View
SPSS has two views:
Always set up Variable View first. For each variable, you need to specify:
Coding Categorical Variables
If your variable is categorical (e.g., gender, ethnicity, treatment group), you must code it numerically. For example: Male = 1, Female = 2. Then use the Values column in Variable View to label these codes so your output is readable.
Common Statistical Tests in UK Dissertations
Descriptive Statistics
Run these first for every dataset. Go to Analyze → Descriptive Statistics → Descriptives. This gives you mean, standard deviation, minimum, and maximum for each variable.
Independent Samples t-Test
Use this to compare means between two independent groups (e.g., male vs female scores). Go to Analyze → Compare Means → Independent Samples T-Test. Move your continuous variable to Test Variable(s) and your grouping variable to Grouping Variable.
One-Way ANOVA
Use ANOVA when you are comparing means across three or more groups. Go to Analyze → Compare Means → One-Way ANOVA. If the result is significant, run a post-hoc test (Tukey is standard in UK academic work) to find which groups differ.
Pearson Correlation
Use this to measure the relationship between two continuous variables. Go to Analyze → Correlate → Bivariate. Check Pearson, flag significant correlations, and report the r value and p value.
Chi-Square Test
Use chi-square when both variables are categorical. Go to Analyze → Descriptive Statistics → Crosstabs, then click Statistics and select Chi-square.
Multiple Regression
Use this to predict an outcome variable from two or more predictors. Go to Analyze → Regression → Linear. The R² value tells you how much variance your predictors explain.
How to Report SPSS Results in APA/Harvard Style
UK universities typically require APA or Harvard style for statistical reporting. Here is the standard format:
Always report exact p values rather than just "p < .05" — this is the current APA 7 recommendation and most UK universities now require it.
Checking Assumptions Before Running Tests
Every parametric test has assumptions that must be checked:
If your data violates normality, switch to the non-parametric equivalent: Mann-Whitney U instead of t-test, Kruskal-Wallis instead of ANOVA, Spearman instead of Pearson.
