Answer
### To determine meaningful differences between two groups in a study, conduct a statistical analysis using hypothesis testing methods, and consider correlation coefficients, scatterplots, and validity assessments.
Explanation
## Step1: Identifying the method to determine differences### To determine whether there are meaningful differences between two groups, we should use statistical analysis methods such as hypothesis testing.## Step2: Correlation Coefficient### The correlation coefficient measures the strength and direction of association between two variables.## Step3: Scatterplot### A scatterplot graphically shows the relationship between two variables, often used to assess correlation visually.## Step4: Validity Assessment### Validity assessment involves determining whether the statistical test measures what it is supposed to measure accurately.
