What is the difference between cross-sectional and longitudinal research? - ANSWER: Cross-sectional
research compares different groups at the same time, while longitudinal research follows the same
group over an extended period.
What is the definition of hindsight bias? - ANSWER: Hindsight bias is the tendency to believe an event
was predictable after it occurred.
What is the purpose of an operational definition? - ANSWER: An operational definition defines a
variable in terms of how it is measured.
What is the role of critical thinking in research? - ANSWER: Critical thinking involves objective analysis
and evaluation of an issue.
What is the importance of replication in research? - ANSWER: Replication involves repeating a
research study to confirm the results.
What is the difference between naturalistic observation and a case study? - ANSWER: Naturalistic
observation involves observing behavior in its natural setting, while a case study is an in-depth
analysis of an individual or small group.
What is the definition of a population in research? - ANSWER: A population refers to all individuals in
a particular group of interest.
What is the purpose of a survey in research? - ANSWER: A survey is a data collection method using
questionnaires or interviews.
What is the difference between random assignment and random sampling? - ANSWER: Random
assignment involves assigning participants to experimental groups by chance, while random sampling
involves selecting a sample from a population at random.
What does the correlation coefficient measure? - ANSWER: The correlation coefficient is a statistical
measure of the relationship between variables.
What is the potential issue with sampling bias? - ANSWER: Sampling bias can lead to unrepresentative
results in a study.
What is the purpose of an experiment in research? - ANSWER: An experiment involves manipulating
variables to observe their effects.
What is the difference between correlation and causation? - ANSWER: Correlation refers to a
relationship between variables, while causation refers to a cause-and-effect relationship.
What is the purpose of a double-blind procedure? - ANSWER: A double-blind procedure ensures that
neither the participants nor the researchers know who is in the control or experimental group.
What are research ethics? - ANSWER: Research ethics are guidelines for conducting ethical research.
What is the role of a control group in an experiment? - ANSWER: A control group is a group that is not
exposed to the independent variable.
