Go to Data → Data Analysis → t-Test: Two-Sample Assuming Equal Variances (or Unequal if unsure).
Variable 1 Range: Select Male column (without header).
Variable 2 Range: Select Female column (without header).
Hypothesized Mean Difference: 0 (default).
Alpha: 0.05 (95% confidence).
Choose an output range (e.g., a blank cell).
Click OK.

Step 3: Run t-Test

Go to Data → Data Analysis → t-Test: Two-Sample Assuming Equal Variances (or Unequal if unsure).
Variable 1 Range: Select Male column (without header).
Variable 2 Range: Select Female column (without header).
