Types of research sampling methods

Identify the research problem clearly and justify its selection, particularly in relation to any valid alternative designs that could have been used.For example, with longitudinal surveys, the same group of people is interviewed at regular intervals, enabling researchers to track changes over time and to relate them to variables that might explain why the changes occur.If two variables are correlated, the cause must come before the effect.May generate new knowledge new insights or uncover hidden insights, patterns, or relationships that a single methodological approach might not reveal.

A researcher must be proficient in understanding how to apply multiple methods to investigating a research problem as well as be proficient in optimizing how to design a study that coherently melds them together.

Experimental Design: Procedures for the Behavioral Sciences. 4th edition.Either original data or secondary data can be used in this design.It is generally not expensive, time consuming, or workforce intensive.

While longitudinal studies involve taking multiple measures over an extended period of time, cross-sectional research is focused on finding relationships between variables at one moment in time.Causal Case Study Methods: Foundations and Guidelines for Comparing, Matching, and Tracing.Understood more as an broad approach to examining a research problem than a methodological design, philosophical analysis and argumentation is intended to challenge deeply embedded, often intractable, assumptions underpinning an area of study.The purpose of a historical research design is to collect, verify, and synthesize evidence from the past to establish facts that defend or refute a hypothesis.Research Design: Creating Robust Approaches for the Social Sciences.Qualitative research is collecting, analyzing and interpreting data by observing what people do and say.Social scientists, in particular, make wide use of this research design to examine contemporary real-life situations and provide the basis for the application of concepts and theories and the extension of methodologies.

This type of research is done by an individual company for the problem faced by it.

Meta-analysis is an analytical methodology designed to systematically evaluate and summarize the results from a number of individual studies, thereby, increasing the overall sample size and the ability of the researcher to study effects of interest.
