Which of the following is NOT a type of psychological research method?

Case study

Experimental design

Survey research

Logical reasoning

What is the purpose of informed consent in psychological research?

To provide participants with information about the research study

To manipulate the independent variable

To measure the dependent variable

To ensure the control group is properly selected

What is the purpose of debriefing participants in psychological research?

To provide participants with informed consent

To manipulate the independent variable

To ensure participant confidentiality

To inform participants about the true nature of the study after its completion

What is the purpose of descriptive statistics in psychological research?

To summarize and describe the characteristics of a data set

To test hypotheses and determine cause-and-effect relationships

To infer population parameters from sample data

To determine the statistical significance of results

What is the purpose of a frequency distribution in psychological research?

To summarize and describe the characteristics of a data set

To test hypotheses and determine cause-and-effect relationships

To infer population parameters from sample data

To determine the statistical significance of results

What is the primary purpose of random assignment in experimental design?

To ensure participants are from the same demographic

To assign participants to different groups without bias

To manipulate the independent variable

To measure the dependent variable

What is a confounding variable in an experiment?

A variable that affects the dependent variable but is not controlled for

A variable that is manipulated by the researcher

A variable that is measured by the researcher

A variable that is irrelevant to the experiment

What is the difference between correlation and causation?

Correlation indicates a relationship between variables, while causation implies that one variable directly influences the other.

Correlation refers to experimental research, while causation refers to observational research.

Correlation only involves quantitative data, while causation involves qualitative data.

Correlation and causation are synonymous terms.

Which of the following is an example of a quasi-experimental design?

A double-blind study

A longitudinal study

A pretest-posttest design

A randomized controlled trial

#10

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

To test the feasibility of the research design

To manipulate the independent variable

To analyze the results of the study

To select participants for the main study

#11

What is internal validity in experimental research?

The extent to which the results can be generalized to other populations

The degree to which the experimental manipulation produces the intended effects

The likelihood that the observed effects are due to chance

The degree to which the study accurately measures what it intends to measure

#12

Which of the following is a disadvantage of experimental research?

It allows for the establishment of cause-and-effect relationships

It can be difficult to generalize findings to real-world settings

It is less time-consuming compared to other research methods

It does not involve manipulation of variables

#13

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

To receive the experimental treatment

To serve as a baseline for comparison

To manipulate the independent variable

To ensure random assignment

#14

Which of the following is a potential ethical issue in psychological research?

Using deception without debriefing participants

Providing participants with informed consent

Ensuring participant confidentiality

Conducting research in controlled laboratory settings

#15

What is the difference between a correlation coefficient and a regression coefficient?

There is no difference; they both measure the strength and direction of a relationship between variables

A correlation coefficient measures the strength and direction of a relationship, while a regression coefficient predicts the value of one variable based on another

A regression coefficient measures the strength and direction of a relationship, while a correlation coefficient predicts the value of one variable based on another

A correlation coefficient is used in experimental research, while a regression coefficient is used in observational research
