- PARAMETERS specifies that both group sizes are set to 2, the pooled
population standard deviation is set to 1, both group means are set to 2, and the significance level
uses the default 0.05 value.
- CONTRAST specifies that estimating the power of testing
for the pairwise differences is enabled and the adjustment of multiple comparisons uses the
Bonferroni correction in estimating the power of pairwise differences.
- PLOT specifies that the two-dimensional power by total sample size chart
displays in the output. The three-dimensional power by total sample size (x -axis) and pooled
standard deviation (y-axis) chart also displays in the output. The vertical and horizontal rotation
settings use their default values (10 degrees and 325 degrees respectively).
