Quantity and Quality in Social Research by Alan Bryman
The professional literature on social research has been enriched by Alan Bryman’s book entitled Quality and Quantity in Social Research. As its title suggests, this book addresses the important consideration of both quality and quantity when designing, conducting, andanalyzing social research. Alan Bryman’s book offers readers a comprehensive look at the intersection of both approaches while emphasizing the importance of a holistic approach that combines both quality, in terms of measuring meaningfully, and quantity, in terms of representing larger populations.
The first chapter of the book addresses contemporary data collection methods in social research, emphasizing the importance of particular research designs to achieve meaningful results. Alan Bryman explains that, in order to gain an accurate understanding of the subject of interest, there are a few questions that the researcher should ask: What is the research design?, What is the nature of the data collection?, What is the sample size and other issues relating to the generalisability of the results? By taking into consideration the answers to these questions, one is able to develop a research design that takes into consideration both quality and quantity.
Subsequent chapters cover important topics related to the theme of quantity and quality in social research. In chapter two, Alan Bryman discusses the importance of representing the right sample and sample size in research. He distinguishes between random sampling, considered the gold standard of data collection, and non-random sampling which is less dependable yet may be used when budget and time are limited. He speaks to issues related to sample size and representative populations, making the point that a sample size and population should be selected that reflects the population of interest.
In chapter three, Alan Bryman examines internal validity and external validity, two important facets of research quality. He describes internal validity as the degree to which a research design processes are effective in producing valid inferences from the data, while external validity relates to the degree to which the study results can be applied to other populations. In chapter four, he further expands on the concepts of internal and external validity by discussing the significance of matching controls with comparison groups and the importance of using random assignment of groups to control for potential sources of bias.
The final chapters of the book focus on the analysis of collected data. Bryman speaks to qualitative and quantitative data, describing the strengths and weaknesses of both approaches. He emphasizes the importance of valid analytical techniques, showing how the selection of appropriate techniques can render more meaningful results. Furthermore, he covers the importance of accuracy in data entry and coding, as well as descriptive analysis of data in both qualitative and quantitative perspectives.
Overall, Alan Bryman’s book Quality and Quantity in Social Research offers readers an in-depth exploration of the importance of combined quality and quantity when conducting social research. The book covers various concepts related to data collection, including sample selection, control groups, and validity assessment. Moreover, the book offers practical guidance on proper data analysis and interpretation, helping readers to understand how collecting data that combine quality and quantity is essential for carrying out meaningful social research.
