#1
Which of the following best describes longitudinal research?
A study examining the same subjects over an extended period
ExplanationLongitudinal research involves studying the same subjects over a prolonged duration.
#2
What is the primary advantage of longitudinal research?
It allows for the examination of changes over time
ExplanationLongitudinal research enables the analysis of changes in variables across time periods.
#3
Which of the following is a potential challenge of longitudinal research?
Increased likelihood of participant dropout
ExplanationOne challenge of longitudinal research is the higher risk of participants dropping out over the study duration.
#4
In longitudinal research, what does attrition refer to?
The loss of participants over the course of the study
ExplanationAttrition in longitudinal research refers to the gradual loss of participants during the study.
#5
What is a cohort in longitudinal research?
A group of participants selected based on a specific characteristic or experience
ExplanationA cohort in longitudinal research is a group of participants chosen due to a shared characteristic or experience.
#6
Which of the following is NOT a potential benefit of longitudinal research?
Providing quick results
ExplanationLongitudinal research doesn't offer quick results; it focuses on studying changes over an extended period.
#7
What is the term used to describe the phenomenon where participants may change their behavior due to being observed or studied over time?
Hawthorne effect
ExplanationThe Hawthorne effect refers to participants altering their behavior when aware of being observed or studied.
#8
Which of the following is a limitation of longitudinal research?
It may suffer from sample bias
ExplanationLongitudinal research may be prone to sample bias, limiting the generalizability of results.
#9
Which type of longitudinal study involves collecting data from the same subjects at different points in time?
Panel study
ExplanationA panel study in longitudinal research collects data from the same subjects at multiple time points.
#10
Which of the following is a key consideration when designing a longitudinal study?
Minimizing attrition
ExplanationMinimizing attrition is crucial in designing longitudinal studies to maintain the integrity of the data.
#11
What statistical technique is commonly used to analyze longitudinal data?
Longitudinal regression
ExplanationLongitudinal regression is a common statistical technique employed for analyzing data in longitudinal studies.
#12
Which of the following is a type of bias that can affect longitudinal research?
Selection bias
ExplanationSelection bias is a type of bias that can impact the validity of findings in longitudinal research.
#13
What term is used to describe the statistical technique used to analyze changes in variables over time within the same subjects?
Time series analysis
ExplanationTime series analysis is the statistical technique used to examine changes in variables over time within the same subjects.
#14
In longitudinal research, what is the term for when the effects of one variable are confounded with another variable that changes over time?
Temporal confounding
ExplanationTemporal confounding in longitudinal research occurs when the effects of one variable are mixed with changes in another variable over time.
