What are the strengths and weaknesses of independent measures design?
Advantages of independent measures design include less time/money involved than a within subjects design and increased external validity because more participants are used. A disadvantage is that individual differences in participants can sometimes lead to differences in the groups’ results.
What is a strength of independent groups design?
A strength of the independent measures design is that because participants only take part in one condition participants are less likely to become border or practiced and therefore the experiment is more likely to measure natural real-life behaviour.
What are the weaknesses of an independent groups design?
Independent groups design
| Independent groups design | |
| Advantages No order effects Lower risk of demand characteristics Same tests/materials can be used | Disadvantages Participant variables More participants required than with repeated measures design |
| Evaluation |
What is the strengths and weaknesses of experimental research?
Advantages and Disadvantages of Experimental Research: Quick Reference List
| Advantages | Disadvantages |
|---|---|
| intuitive practice shaped by research | personal bias of researcher may intrude |
| teachers have bias but can be reflective | sample may not be representative |
| researcher can have control over variables | can produce artificial results |
What are the disadvantages of independent measures?
Independent Measures: Con: More people are needed than with the repeated measures design (i.e., more time consuming). Pro: Avoids order effects (such as practice or fatigue) as people participate in one condition only.
What are the limitations of independent measures design?
Disadvantages
- researcher cannot control the effects of participant variables (i.e. different characteristics or abilities of each participant). This would cause a confounding variable.
- needs more design than the Repeated Measures Design in order to end up with the same amount of data.
What is independent group design?
Independent groups design is an experimental design where different participants are used in each condition of the experiment.
What are the advantages and disadvantages of repeated measures design?
Repeated measures
| Repeated measures | |
| Advantages No participant variables fewer participants required than when using other designs | Disadvantages Order effects- boredom, fatigue, practice Demand characteristics more likely Different tests and materials may be required for each condition |
| Evaluation |
What are the advantages and disadvantages of opportunity sampling?
Opportunity Sampling
| Opportunity Sampling | |
| Advantages Quick Easy Cheap | Disadvantages Biased Cannot be generalised Researcher has control over selection |
| Evaluation Although it is the easiest method, opportunity sampling is biased and cannot be generalised |
What are the strengths of experimental research design?
What Are the Advantages of Experimental Research?
- It provides researchers with a high level of control.
- There is no limit to the subject matter or industry involved.
- Experimental research provides conclusions that are specific.
- The results of experimental research can be duplicated.
What is the one weakness of the experimental research design?
Weaknesses: The main weakness of the experimental method is their dependence on what many see as an “artificial” environment. People may behave differently in the experimental setting than they would under more ordinary conditions.
What is an independent group design?
What is an advantage of using independent groups design?
What is an advantage of using independent groups design? Advantages of independent measures design include less time/money involved than a within subjects design and increased external validity because more participants are used. A disadvantage is that individual differences in participants can sometimes lead to differences in the groups’ results.
What are the strengths of an experimental design?
Experimental Design Strengths Experimental designs sets the precedence for being the first standard prototypes for researchers. Researchers can regulate independent variables and dispose of superfluous variables more so than other research design methods.
What does between groups mean in experimental design?
This type of design is also known as between groups. 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.
What are the advantages of independent measures design?
Advantages of independent measures design include less time/money involved than a within subjects design and increased external validity because more participants are used. A disadvantage is that individual differences in participants can sometimes lead to differences in the groups’ results.
