Factorial Design Example 1

• Two studies, 3 conditions A, B, C (some repeated), block
  • study 1: 6 subjects
  • study 2: 3 subjects
• The regions of significance are those where the null hypothesis Ho:(C2-A2)-(C1-A1)<=0 can be rejected.
• This “difference of differences” is the only allowable contrast form for between study comparisons.
