Laura is designing a study that examines difference in social skills between children raised in a three-generation family household compared to those raised in a two-generation family home. Laura is most likely to study this research problem by use of causal-comparative research because
◦ she will not attempt to explain any reasons for differences in social skills.
◦ the events have already happened.
◦ she wants to manipulate the independent variable, type of home environment.
◦ she will only address relationships and not levels of an independent variable.
