In an experiment, what is the independent variable?

The variable that is measured

The variable that is manipulated

The variable that remains constant

The variable that is affected by the independent variable

Which type of variable is the one that is directly manipulated by the researcher?

Dependent variable

Independent variable

Confounding variable

Extraneous variable

Which of the following is NOT a type of research design?

Correlational research

Experimental research

Descriptive research

Predictive research

What is random assignment in experimental research?

Assigning participants to different groups based on a predetermined criterion

Assigning participants to different groups based on chance

Assigning participants to different groups based on their preferences

Assigning participants to different groups based on their characteristics

What is the purpose of a control group in an experiment?

To provide a baseline for comparison

To ensure ethical standards

To ensure that the experiment is double-blinded

To eliminate extraneous variables

What is the difference between an independent variable and a dependent variable?

The independent variable is manipulated, while the dependent variable is measured

The dependent variable is manipulated, while the independent variable is measured

There is no difference between them

They are both manipulated by the researcher

What is the difference between a population and a sample in research?

There is no difference between them

A population refers to a specific group, while a sample is a subset of that group

A sample refers to a specific group, while a population is a subset of that group

A population is used in qualitative research, while a sample is used in quantitative research

What is a placebo in experimental research?

A treatment that has no therapeutic effect

A treatment that has a known therapeutic effect

A treatment that is administered to the control group

A treatment that is administered to the experimental group

What is a within-subjects design in experimental research?

An experimental design where each participant is only tested once

An experimental design where each participant is tested multiple times

An experimental design where participants are randomly assigned to different groups

An experimental design where participants are matched based on certain characteristics

#10

Which of the following is a potential disadvantage of a between-subjects design?

Higher statistical power

Order effects

Participant attrition

Increased demand characteristics

#11

What are extraneous variables in an experiment?

Variables that are directly manipulated by the researcher

Variables that are measured as outcomes of the experiment

Variables that are irrelevant to the study but can affect the results

Variables that are controlled in the experimental design

#12

What is a confounding variable in an experiment?

A variable that is directly manipulated by the researcher

A variable that is irrelevant to the study but can affect the results

A variable that is measured as an outcome of the experiment

A variable that is controlled in the experimental design

#13

What is a double-blind procedure in experimental research?

When neither the participants nor the researchers know who is in the control group

When only the participants know who is in the control group

When only the researchers know who is in the control group

When both the participants and the researchers know who is in the control group

#14

In a factorial design, how many independent variables are manipulated?

One

Two or more

None

It depends on the specific design

#15

What is the purpose of counterbalancing in experimental research?

To ensure that each participant receives the same treatment

To minimize the effects of extraneous variables

To control for order effects

To increase the generalizability of the results

#16

What is the difference between internal validity and external validity in research?

Internal validity refers to the generalizability of findings, while external validity refers to the accuracy of measurements.

Internal validity refers to the accuracy of measurements, while external validity refers to the generalizability of findings.

Internal validity refers to the accuracy of measurements within the study, while external validity refers to the generalizability of findings beyond the study.

Internal validity refers to the generalizability of findings beyond the study, while external validity refers to the accuracy of measurements within the study.
