...This volume begins with the intricacies involved in the designing of a research project. Ruth A. Wienclaw explains what constitutes “good” research design and how to limit extraneous variables. An important stage in this process is hypothesis construction, which is the first step in testing the validity of a theory. The reference guide then details the various methods sociologists employ in their gathering of data. Collecting field data, surveying individuals, sampling 
 populations, and conducting experiments are just a few examples of popular collection techniques. However, for data to be useable, all collection instruments and measures must be reliable and valid. An analysis of choosing proper means for data collection is examined in the volume’s essay on reliability. Alexandra Howson then expounds upon the use of quantitative and qualitative research and evaluation methods, which provide important paradigms in the research of social and behavioral science. 
 In addition to the components involved in the gathering of data, the tools used in the analysis and understanding of research must also be taken into account. Probability theory can determine the likelihood that a hypothesized relationship between variables exists, but it does not necessarily prove that this hypothesis is correct. It does, however, help for expressing the level of confidence in the variable relationship. The types of variables that can play significant roles in hypothesis testing include independent variables, extraneous variables, intervening variables, and dependent variables. As statistical analysis with regard to sociological studies become more in-depth, studies on confidence intervals and correlation become more relevant. This volume covers several of these statistical topics, including inferential statistics, which allow sociologists to draw conclusions from data that are worth testing, and descriptive statistics, which allow individuals to better understand masses of data. This reference guide concludes with Wienclaw’s examinations of the unethical use of statistics and the importance and necessity of maintaining proper ethics when conducting research in sociology...
