An introduction to the conventions of research design and statistical analysis is presented for graduate students of applied linguistics. The chapters cover such concepts as the definition of research, variables, research designs, research report formats, sorting and displaying data, probability and hypothesis testing, comparing means, correlational analyses, linear regression, reliability and validity, and factor analysis. Examples are drawn from bilingual education, English as second language instruction, and language policy and planning research. Each chapter includes problems, activities, and guidelines for working with a computer. Also provided are a pretest for determining where in the text more advanced students should begin, a glossary of symbols, statistical tables, and a list of formulas. (RW)
