Question

Quizplus · Accepted Answer

Cross-sectional studies involve comparing groups of people of different ages at the same time, which can produce cohort effects. Cohort effects occur when differences between age groups are due to factors other than age itself, such as historical events or cultural changes that affect individuals of a certain generation. Cohort effects can be avoided in longitudinal studies, which track changes in the same group of individuals over time, or experimental studies, where participants are randomly assigned to different conditions. Correlational studies do not necessarily involve age comparisons and do not inherently involve cohort effects.
