Comparison of Group Means

Awaiting validation
The script begins by setting a global title for the output. It then initializes a dataset named 'Scores' by directly providing gender and score data via the `datalines` statement. The TTEST procedure is executed twice to compare the mean of 'Score' between 'Gender' categories. ODS statements are present but commented out, indicating an intention for output management (HTML, PDF) that is not active in this version of the code.
