EXPERIMENTAL DESIGNS Flashcards
WHAT ARE THE 3 EXPERIMENTAL DESIGNS
between subjects, within subjects and mixed design
BETWEEN SUBJECT DESIGN
ADVANTAGES AND LIMITATIONS OF BETWEEN SUBJECT DESIGN
ADVANTAGE: QUICKER
LIMITATION: OFTEN NEEDS A LARGER SAMPLE
WITHIN SUBJECT DESIGN
EACH PARTICIPANTS ARE IN BOTH THE EXPERIMENTAL GROUP AND CONTROL GROUP, EACH GROUP COMPLETE BOTH THE CONTROL AND EXPERIMENTAL CONDITIONS. THEN WE SEE IF THE IV HAD EFFECT ON DV.
ADVANTAGES AND LIMITATIONS OF WITHIN SUBJECT DESIGN
ADV: REQUIRED SMALL NUMBER OF PARTICIPANTS IN THE DESIGN BECAUSE ALL PARTICIPANTS ARE DOING BOTH CONDITIONS
LIM: POSSIBLY CAN GAIN PRACTICE ONCE DOING THE EXPERIMENT THE 2ND TIME
MIXED DESIGN
COMBINES BOTH BETWEEN SUBJECT DESIGN AND WITHIN SUBJECT DESIGN
(BEFORE AND AFTER)
ADV AND LIM OF MIXED DESIGN
ADV: FEWER PARTICIPANTS NEEDED
LIM: HIGHER RATES OF PARTICIPANTS WITHDRAWL

WITHIN SUBJECT, BETWEEN SUBJECT AND MIXED DESIGN.
