What is the purpose of gathering subjects into equivalent groups in experimental research?
To compare the effect of one condition on another group or to compare the effect of different conditions on the same group.
What does the manipulation of independent variables involve in experimental research?
The independent variable, or cause, is manipulated by assigning values or conditions by the researcher.
What is the role of inferential statistics in experimental research?
Inferential statistics allow decisions to be made in terms of probability to make further generalizations.
Why is the use of two groups important in experimental research?
It allows for comparing the effect of one condition on another group or comparing the effect of different conditions on the same group.
What is the purpose of random allocation of subjects in experimental research?
To gather subjects into equivalent groups for comparison purposes.
What does experimental research involve in terms of comparing conditions?
Comparing the effect of one condition on another group or comparing the effect of different conditions on the same group.
What is the role of the independent variable in experimental research?
It is manipulated to measure its effect on the dependent variable.
What do inferential statistics allow in experimental research?
They allow decisions to be made in terms of probability to make further generalizations.
Study Notes
Experimental Research Methods
- The most used method for gathering subjects into equivalent groups in experimental research is randomization, which ensures that the groups are similar in all aspects except for the independent variable.
Importance of Two Groups
- The need for two groups, an experimental group and a control group, is important in experimental research because it allows researchers to compare the effects of the independent variable on the dependent variable.
Independent Variable Manipulation
- The manipulation of independent variables involves intentionally changing the independent variable to observe its effect on the dependent variable, while controlling for other variables.
Inferential Statistics
- Inferential statistics allow researchers to make inferences about the population based on the sample data, and to determine whether the results are due to chance or the effect of the independent variable.
Purpose of Equivalent Groups
- The purpose of gathering subjects into equivalent groups is to control for extraneous variables and to ensure that the groups are similar in all aspects except for the independent variable.
Role of Independent Variable
- The independent variable is manipulated by the researcher to observe its effect on the dependent variable.
Purpose of Random Allocation
- The purpose of random allocation of subjects is to minimize bias and ensure that the groups are equivalent.
Comparing Conditions
- Experimental research involves comparing the conditions of the experimental and control groups to determine the effect of the independent variable.
Role of Inferential Statistics
- The role of inferential statistics is to analyze the data and determine the significance of the results.
