Independent variable is the factor that the researcher manipulates conditions that will allow them to manipulate a particular independent variable: randomly assigns respondents to groups. Same is true for sex, ethnicity, or social class differences (no cause-and-effect conclusion) In a process called terminal decline, individuals gradually lose cognitive abilities as they draw closer to death. Or is it better to compare people at the two extremes of the adult span: the possibility that different age groups will react differently to the test materials, quick and inexpensive. Sequential research designs: these designs consist of different combinations of the variables age, cohort, and time of measurement.
