Q1)a) Categorize according to most descriptive or definitive category of research strategies (i.e., experiments, naturalistic observations, surveys, case-control studies, cohort studies, quasi-experiments, longitudinal vs. cross-sectional studies, matched design, retrospective vs. prospective studies, time-series, single-subject studies).

b) Recognize features of study that prompted your classification.

c) Recognize the IV, DV, and other variables, if suitable.

d) Recognize and describe potential threats (up to 3) to internal validity.

e) Recognize and explain potential threats (up to 3) to external validity.

f) Recognize strategies that were utilized to control for nuisance variables and minimize threats to valid inference making.

g) What additional strategies (up to 3) you would propose that may increase validity of the findings

The effect of smoking during mothers' pregnancy on children's delinquent behavior was investigated for a random sample of 300 kids who were junior high students in a local community. The kids were classified as ever having been arrested (yes/no). Their mothers were then interviewed to determine if they smoked while they were pregnant with these kids.
