A complete range of research tools as well as descriptive and inferential statistics are also included, making this text the definitive resource for introductory research courses. Research in Education is divided into three parts: Part I, "Introduction to Educational Research," focuses on the purpose of research, hypotheses, developing a research problem, and writing proposals and reports; Part II, "Research Methods," is unique in that it integrates chapters on qualitative research methods, historical research and single-subject methods with the more typical chapters on experimental methods; and Part III, "Data Analysis," includes both descriptive and inferential statistics, as well as examples of analysis using a computer.
