Questions With All Correct Updated
Answers.
Single-Factor Randomized, Two Groups - Answer One IV with 2 Levels / Between-Subjects Design
Procedure:
1.) Participants are randomly assigned to two groups [ie: experimental and control]
2.) This is analyzed via a between-subjects t-test
Disadvantage:
*They cannot detect a non-linear effect*
Single-Factor Randomized, Multiple Groups - Answer One IV with 3 or more Levels / Between-Subjects
Design
Procedure:
1.) Participants are randomly assigned into groups
2.) This is analyzed via an ANOVA (analysis of variance), one-way between subjects design
Important Notes:
*The ANOVA is used instead of multiple t-test because these could increase Type I Error
, *If ANOVA shows a significant main effect of the IV, post-hoc tests need to be utilized to pinpoint specific
differences.
Matched Groups Design - Answer Used when random assignment is not sufficient to control individual
differences.
Procedure:
1.) Measure participants for a certain characteristic [ie: IQ]
2.) Match participants according to the characteristic (ie: pair those with similar IQ scores) to form pairs
3.) Randomly assign one participant from each pair to the control group and the other to the
experimental group
Within-Subjects Designs - Answer Used when participants are exposed to all levels of the IV.
Procedure:
1.) Analyze changes in behavior within participants across different treatments. This is also called a
"repeated-measures design".
Advantages:
*Reduces error variance due to individual differences
* Fewer participants required
