2. Copy the first 15 distance data values (far right hand column) into the Treatment 1 Box, each line being a separate value.
3. Copy the second 20 testosterone change data values (far right hand column) into the Treatment 2 Box, each line being a separate value.
4. Scroll down and make sure Significance level is marked for .05 and Two-tailed hypothesis is marked.
5. Select Calculate T and P Values
6. Several new boxes will appear with much text.
  1. Scroll down to the Difference Scores Calculations box.
  2. For Treatment 1 it will have M1's value (the mean for the MD data) and the variance for those scores.
  3. For Treatment 2 it will have M2's value (the mean for the WV data) and the variance for those scores.
  4. t will be calculated below that, but also summarized in blue text below the box.
7. Write down
  - the t-value,
  - the associated p-value (Round as you see fit, but I assure you that you do not need 5 decimal places),
  - the two means and
  - two variances.
8. Take the square root of each of the two variances to get standard deviations.

The degrees of freedom for this is 33. N is 35 and N-2 is 33.
