| Repeated Measures Experimental Design (W/In Subjects Design) |
-Type of Experimental Design
• Participants are not assigned to
different manipulations, but to
multiple manipulations
• Effects of one manipulation are
compared to the effects of the
manipulation of another |

| Posttest Only Experimental Design |
-Type of Experimental Design
R X O1
R O1
• No pretest
• If difference at the time of observation is significant, it’s assumed that it’s caused by the treatment |
