Example (POWER MEANS RELATED command)

POWER MEANS RELATED 
  /PARAMETERS TEST=NONDIRECTIONAL SIGNIFICANCE=0.05 NPAIRS=4 SD=.75 MEAN=1 
  /PLOT NPAIRS(2 4) NPAIRS_YAXIS(2 4) ES_XAXIS VROTATE(10) HROTATE(325).

• PARAMETERS specifies that the test is non-directional (two-sided), the significance level uses the default 0.05 value, the number of group pairs for power estimation is set to 4, the population standard deviation is set to 0.75, and the population mean under testing is set to 1.
• PLOT specifies that the two-dimensional power by sample size chart displays in the output. The three-dimensional power by sample size (x -axis) and effect size (y-axis) chart also displays in the output. The vertical and horizontal rotation settings use their default values (10 degrees and 325 degrees respectively).
