#2
What does a correlation coefficient measure?
The difference between two means.
The strength and direction of a relationship between two variables.
The likelihood that a result occurred by chance.
The impact of one variable on another.
#3
What is an independent variable in an experiment?
The outcome that is measured to see how it is changed by manipulations.
The variable that is manipulated to observe its effect on the dependent variable.
A variable that remains constant throughout the experiment.
A variable that is not anticipated but affects the outcome of the experiment.
#4
What is the placebo effect?
The impact of the experimental treatment.
A temporary experimental effect, resulting from the participant's expectations.
The improvement of participants' conditions due to the actual treatment.
The psychological or physiological improvement observed in participants, which results from their expectations of the treatment rather than the treatment itself.
#5
In experimental research, what is the purpose of control groups?
To receive the experimental treatment.
To be observed without any intervention.
To be given a placebo treatment.
To serve as a standard for comparison against the group that receives the experimental treatment.
#6
What is the main advantage of a longitudinal study?
It is quick to conduct.
It provides a snapshot of a population at a single time.
It can reveal development trends and changes over time.
It requires fewer resources than cross-sectional studies.
#7

#8
What does the term 'operational definition' refer to in psychological research?

A clearly defined, observable event that indicates the application of the concept.
The theoretical framework that guides the research.
The operations carried out by the research participants.
#9
In the context of psychological research, what is the primary purpose of random assignment?
To ensure that each participant has an equal chance of being assigned to any group.
To randomly select participants for the study from the population.
To eliminate the need for a control group.
To increase the variability within each group.
#10
Which of the following best defines a case study in psychological research?
A study that measures the effect of a treatment on large groups of people.
An observational technique where one person is studied in depth in the hope of revealing universal principles.
A study that compares the traits of two groups that are different in some critical way.
An experiment where the participants do not know if they are receiving the treatment or not.
#11
Which statistical method is most commonly used to determine if there are significant differences between the means of two groups?

#14
In psychology research, what is the primary purpose of using a Likert scale in questionnaires?
To determine the statistical significance of results.
To measure the intensity of participants' attitudes or feelings about a specific topic.
To assign participants to different groups based on their responses.
To provide a qualitative measure of cognitive abilities.
#15
What is the primary function of inferential statistics in psychological research?
To describe the basic features of the data in the study
To make predictions about a population based on a sample
To organize data into meaningful patterns and summaries
To make judgments that extend beyond the immediate data alone
