Research Methods in Experimental Psychology Quiz

#1

Which of the following is a key characteristic of experimental research?

Manipulation of variables
Explanation

Experimental research involves manipulating variables to observe their effects.

#2

Which type of validity assesses the extent to which the findings can be generalized to other populations?

External validity
Explanation

External validity determines the extent to which study findings can be generalized beyond the sample and setting used in the study.

#3

What is the primary goal of random sampling in experimental research?

To ensure every individual has an equal chance of being in the study
Explanation

Random sampling ensures that every individual in the population has an equal chance of being selected for the study, enhancing the generalizability of findings.

#4

In experimental research, what is the purpose of a research hypothesis?

To guide the research design and predictions
Explanation

Research hypotheses provide a framework for designing experiments and making predictions about the relationship between variables.

#5

What is the independent variable in an experiment?

The variable manipulated by the researcher
Explanation

The independent variable is the one the researcher manipulates to observe its effect on the dependent variable.

#6

Which statistical test is commonly used to compare means between two groups in experimental research?

T-test
Explanation

T-test is used to determine if there is a significant difference between the means of two groups.

#7

In experimental research, what does random assignment refer to?

Assigning participants to groups by chance or random selection
Explanation

Random assignment ensures that each participant has an equal chance of being assigned to any group, minimizing bias.

#8

What is the purpose of a pilot study in experimental research?

To identify potential problems and refine the study design
Explanation

Pilot studies help researchers identify and address any issues with the study design before conducting the main experiment.

#9

What is the purpose of a debriefing session in experimental research?

To provide participants with information about the study's true purpose and nature
Explanation

Debriefing sessions inform participants about the true aims of the study and address any concerns or misunderstandings.

#10

What is a confounding variable in experimental research?

A variable that interferes with the study's results
Explanation

Confounding variables are factors other than the independent variable that may affect the outcome of the study.

#11

What is the purpose of a control group in an experimental study?

To provide a baseline for comparison
Explanation

Control group ensures that any changes observed in the experimental group can be attributed to the manipulation of the independent variable.

#12

What is a double-blind experimental design?

An experiment in which neither the participants nor the researchers know who is in the experimental or control group
Explanation

In a double-blind design, neither the participants nor the researchers know who is receiving the treatment, minimizing bias.

#13

What is a counterbalancing technique in experimental design?

Balancing the order of presentation of experimental conditions across participants
Explanation

Counterbalancing ensures that the order in which experimental conditions are presented does not confound the results.

#14

What is the purpose of a placebo in experimental research?

To control for the effects of participant expectations
Explanation

Placebos help control for the placebo effect by providing participants with an inert substance or treatment.
