- Read the three study descriptions below: Select any two of the studies for this Assignment.
- Study 1 utilized a participant-variable design and demonstrated that women perform more poorly, on average, than men perform on the mathematics section of the Scholastic Aptitude Test (SAT).
- Study 2 utilized a comparison-group before-after design and demonstrated that students from lower socioeconomic status (SES) households benefit more over time from an academic tutoring program than do students from higher SES households.
- Study 3 utilized a cross-sectional design and measured the IQ of individuals who are in their twenties. In Group 1 are 20-year-olds, Group 2 are 24-year-olds, and Group 3 are 29-year-olds. The mean IQ for the three groups is 103, 100, and 90, respectively. Consider whether the researcher can accurately conclude that people lose intelligence as they age.
