What is a case study in psychological research?
A method involving the manipulation of variables to determine cause and effect
An in-depth analysis of an individual, group, or event
A statistical technique for combining the findings from independent studies
A method of observing subjects in their natural environment
Which of the following best describes a correlation coefficient?
A measure of the central tendency of a data set
A numerical value that indicates the strength and direction of a relationship between two variables
A statistical test used to determine the significance of a study
A method for collecting qualitative data
In a scatter plot showing a positive correlation, what trend would you expect to see?
As one variable increases, the other variable decreases
As one variable increases, the other variable also increases
No discernible pattern between the variables
Both variables remain constant
What is a potential issue with correlational studies that can affect the interpretation of results?
They can establish causation
They may have a directionality problem or third variable problem
They always require a control group
They are not useful for predicting relationships
What is the purpose of using a placebo in a control group?
To ensure that participants are aware of the treatment they are receiving
To eliminate the need for a control group
To control for the effects of participants' expectations on the outcome
To increase the sample size of the experimental group
How does a double-blind procedure help in experimental research?
It ensures that only the participants are unaware of the treatment they receive
It prevents both the participants and the experimenters from knowing who receives the treatment
It allows the experimenter to influence the results
It is used only in qualitative research
Which of the following is an example of a non-experimental methodology?
Randomized controlled trial
Naturalistic observation
Laboratory experiment
Field experiment
What is the main difference between qualitative and quantitative measurement instruments in research?
Qualitative instruments use numerical data, while quantitative instruments use descriptive data
Qualitative instruments use descriptive data, while quantitative instruments use numerical data
Both use numerical data
Both use descriptive data
In a study, if the correlation coefficient is −0.85 , what does this indicate about the relationship between the two variables?
A weak positive relationship
A strong negative relationship
No relationship
A strong positive relationship
Why might a researcher choose to use a meta-analysis in psychological research?
To conduct an in-depth study of a single case
To combine data from multiple studies to identify overall trends
To observe behavior in a natural setting
To manipulate variables in a controlled environment
