Detailed explanation-1: -A longitudinal study, like a cross-sectional one, is observational. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years.
Detailed explanation-2: -Cross-sectional research shows a decline in intellectual ability. 4. Longitudinal research usually shows that intelligent in most abilities increase through out early and middle adulthood. Many adults show intellectual improvement over most of adulthood, with not decline, even by age 60.
Detailed explanation-3: -Validity is the extent to which a test measures what it claims to measure. 1 It is vital for a test to be valid in order for the results to be accurately applied and interpreted.
