This document outlines different research methods and designs. It discusses key parts of research including research designs, sampling design, observational design, and statistical analysis. It covers types of research like descriptive, exploratory, and explanatory research. Sampling probability and non-probability sampling are discussed. Observational design focuses on outcome measures, measurement errors, and data collection. Statistical design depends on study design, data type, sample size, and software. Clinical research designs covered include case series, case control studies, cross sectional studies, cohort studies, and experimental studies. Examples are provided.
