1. 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 likely to study this research topic by use of

   causal-comparative research because it is an ex post facto design; the events have already happened.

   descriptive research because she will not attempt to explain any reasons for differences in social skills.

   experimental research because she wants to manipulate the independent variable, type of home environment.

   correlational research because she will address relationships only and not levels of an independent variable.
