Major characteristics of experimental research are:
A. Manipulation of independent variable
B. Inclusion of testing variable
C. Control of intervening variables
D. Treating the dependent variable
E. Pre-test Post-test design
Choose the most appropriate answer from the options given below:

Correct option is A

The major characteristics of experimental research are:
Manipulation of independent variable (A)
Control of intervening variables (C)
Pre-test Post-test design (E)
Experimental research involves manipulating one variable to determine if changes in one variable cause changes in another variable. This method relies on controlled methods, random assignment, and the manipulation of variables to test a hypothesis.
Information Booster:
1. Independent Variable: The variable that is manipulated in an experiment.
2. Dependent Variable: The variable that is measured to see if it is affected by the independent variable.
3. Control Group: A group that does not receive the experimental treatment, used for comparison.
4. Random Assignment: Ensures each participant has an equal chance of being assigned to any group in the experiment.
5. Replication: Repeating the study to confirm the results.
6. Internal Validity: The degree to which an experiment supports clear causal conclusions.
Additional Information:
Inclusion of Testing Variable (B): Refers to any variable included to measure effects but is not specifically a major characteristic.
Treating the Dependent Variable (D): Involves measuring the effects of the manipulation on the dependent variable.
