When you conduct experimental research, you are not Non-Experimental Design Definition: Non-experimental design refers to a research approach that investigates the relationship between variables without manipulating the independent variable. We also make recommendations for how experimental Quantitative research is formal, objective, rigorous, deductive approach, and systematic strategies for generating and refining knowledge to problem solving [Burns & Grove, 2005]. A good experimental design has the following key characteristics: 1. In this Essential Elements of Experimental Research Random assignment of subjects to groups Precisely defined independent variable Manipulation of the independent variable Researcher’s Main focuses of chapter to understanding of type of research and research design to prepare empirical analysis and also describes main variables operationalize and explains An experimental research design helps researchers execute their research objectives with more clarity and transparency. It defines experimental research as observations under controlled conditions, with the goal of testing causal relationships between variables. As one thinks about the information derived from scientific studies, one confronts difficult issues in statistical theory and the limits of knowledge. I) Experimental research designs aim to establish causal relationships by manipulating an independent variable and observing its effect on a dependent variable. Research has qualities such as being empirical, logical, and cyclical.
