Mastering SPSS Analysis: Common Statistical Tests Used in Medical Research

The Backbone of Medical Research

Data analysis is often the most intimidating part of medical research. However, understanding basic statistical tests in SPSS (Statistical Package for the Social Sciences) is crucial for validating your clinical findings.

1. Chi-Square Test

Used to compare categorical variables. For example, comparing the prevalence of diabetes (Yes/No) between males and females.

2. Independent Samples T-Test

Used to compare the means of a continuous variable between two distinct groups. For example, comparing the mean blood pressure between patients taking Drug A vs. Drug B.

3. ANOVA (Analysis of Variance)

Similar to the T-test but used when comparing means across three or more groups. For example, comparing cholesterol levels across low, medium, and high dosage groups.

4. Pearson Correlation

Measures the linear relationship between two continuous variables. E.g., the relationship between BMI and blood sugar levels.
