Question

Quizplus · Accepted Answer

Cohort effects are the most widely discussed threat to the accuracy of longitudinal findings. This refers to the impact of being born in a particular time period or generation, which can influence experiences, behaviors, and attitudes across the lifespan. Cohort effects can create bias in longitudinal studies, as differences observed over time may be due to the characteristics of the cohorts being studied rather than true developmental changes. Practice effects (A) refer to improvements in performance due to repeated testing, selective attrition (C) refers to the loss of participants from a study that is not random and may lead to biased results, and biased sampling (D) refers to the non-random selection of participants, which can also lead to biased results.
