Psychologists are typically interested in finding general answers to questions. Although answers to these questions can be obtained in single pieces of research, it is common for different researchers to address similar research questions. This replication makes it possible to answer research questions through assimilating data from a variety of sources. This process is known as meta-analysis. The use of meta-analysis has exploded over the past 30 years and even just a cursory scan of recent meta-analyses reveals the diversity of questions that it has been used to address: whether temperament differs across gender (Else-Quest, Hyde, Goldsmith, andVan Hulle, 2006), organizational wellness (Parks and Steelman, 2008); maternal employment and children's achievement (Goldberg, Prause, Lucas-Thompson, and Himsel, 2008); marital discord as a predictor of domestic ...
