Introduction to simple experiments
14 important questions on Introduction to simple experiments
What do we call the principle that questions what the the relation is of the two variables what are the levels of association and how is the balance between the two?
What principle questions wether the study design ensures that the causal variable comes before the outcome variable in time?
What principle questions wether the study design rules out other explanations for the result?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How do we call a threat to internal validity in the form of confusion about whats causing the change in the dependent variable.
How do we call the principle of getting asymmetrical groups as a cause of letting participants choose which group they can be in?
How do you get matched groups?
What is the difference between an independent-groups design and a within-groups design?
a within-groups design has one group which is presented to both levels of the independent variable.
What is the difference between a posttest design, and a pretest/posttest design?
How do we call a type of design in which participants are measured multiple times on a dependent variable.
How do we call a design where participants are exposed to both sides of the independent variable at the same time?
How do we call the effect which describes the fact that participants can be influenced by exposure to one level of the independent variable in responses on the next level in a within group experiment?
What are practice effects?
What are carryover effects?
How do you call the procedure where researcher avoid order effect by giving each participant a different order of the levels of the independent variable?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
