10] Types Of Experimental Design Flashcards
Experimental Design: What is an independent group design
It is an experimental design that consists of two separate groups being exposed to different experimental conditions.
Usually one half of the participants are assigned to the experimental group where they are exposed to a condition where the independent variable is manipulated.
Experimental Design: What is an repeated measures design
This is where all the participants of a study are involved in all the conditions of an independent variables.
Every circumstance of the experiment contains the exact same group of participants
What are the types of experimental design
1: independent groups
2: repeated measures
What is a hypothesis
It is an idea or explanation for something that is based on known facts but have not yet been proven
What is order and effect mean
A systematic error caused by the order in which participants take part in conditions
E.g: Participants may improve on the second condition because of practice or the might preform worse because they are bored or tired
What does counterbalancing do
It’s a technique used to minimize order effects when conducting usability testing or experiments
Independent Groups: pros
1: Counterbalancing isn’t an issue as every subject is in just one group
2: Researchers can ignore practice and fatigue effect
3:
4:
Independent Groups: Cons
What is randomizing and matching
What is Quasi-experiments
What is non-experimental
What are the types of Quasi-experiments
1: Pretest-post test non-equivalent design
What are the types of non-experiments
1: Differential
2: Post-test only non-equivalent control group
3: One group pretest-posttest
What is differential research
What is post-test only non-equivalent control group
