Experimental Designs Flashcards
What ate the five experimental designs?
Two Independent Groups Design
Two Matched Groups Design
Within-subjects/Repeated-Measures Design
Multiple Groups Design
Factorial Designs
_ refers to how participants are allocated to the different groups in an experiment.
Experimental Design
The purpose of _ is to minimize extraneous or uncontrolled variation.
Experimental Designs
In the types of experimental designs, _ also known as _, isan experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.
Independent Measures Design/Between-Groups Design
In the types of experimental designs, this design has the following drawbacks:
1. Deal with the differences among people and decreases its efficiency.
2. Minimize differences among the subjects in the treatment groups
3. Ensure that both groups are equivalent at the start of the experiment
Independent Measures Design/Between-Groups Design
What is being described in the statement:
In the simplest type of experiment, we create two groups that are “equivalent” to each other.
Equivalent Groups
_ are used to form pars of subjects that had equal or very similar scores.
Baseline Scores
_ is where each person participating in an experiment has an equal chance of being assigned to any particular group.
Randomization
In the types of experimental designs, _ is where pairs of participants are matched in terms of key variables (age, or socioeconomic status). One member of each pair is then placed into experimental group and the other member into control group.
Matched Groups Design
In the types of experimental designs, _ is where same participants take part in each condition of the independent variable. Each condition of the experiment includes the same group of participants.
Within-subjects/Repeated Measures Design
_ is the risk in a within-subjects design where participants may be proficient in learning, may be prone to boredom and have fatigue with the task.
General Practice Effects
To control the general practice effects, you need to perform _.
Counterbalancing
_ tis the effect of the early part of the experiment on the later part of the experiment varies depending on what treatment comes first.
Carryover Effects
A _ isan effect of being tested in one condition on participants’ behavior in later conditions.
carryover effect
One type of carryover effect is a _, where participants perform a task better in later conditions because they have had a chance to practice it.
