EXPERIMENTAL DESIGN Meaning and
Definition
-
Experimental design is a methodological framework used in scientific studies to determine the most efficient and reliable approach to investigating hypotheses or answering research questions. It involves carefully planning and organizing various aspects of an experiment to ensure valid and meaningful results. Experimental design considers factors such as sample size, control groups, independent and dependent variables, randomization, and statistical analysis protocols.
At its core, experimental design aims to establish cause-and-effect relationships between variables by rigorously controlling potential confounding factors. This helps researchers draw meaningful conclusions about the impact or influence of the independent variable on the dependent variable. In experimental design, the independent variable is the factor being manipulated or changed, while the dependent variable is the response or outcome that is measured or observed.
The design typically involves creating experimental and control groups that are as similar as possible, except for the presence or absence of the independent variable. Random assignment of participants to these groups helps ensure that any observed differences in the dependent variable can be attributed to the independent variable rather than other factors.
Experimental design often employs statistical analysis techniques to determine if the observed differences between groups are statistically significant, meaning they are unlikely to have occurred by chance. Various statistical tools like t-tests, ANOVA (analysis of variance), or regression analysis are used to examine and interpret the data collected during the experiment.
Overall, experimental design is a systematic approach that guides researchers in creating well-structured experiments with a high level of internal validity, allowing for more accurate conclusions about the causal relationships between variables.

Etymology of EXPERIMENTAL DESIGN
The word "experimental" comes from the Latin word "experimentum", which means a trial or test. It is derived from the verb "experiri", which means to try or test. The word "design" has its roots in the Latin word "designare", meaning to mark out, designate, or draw. In the context of "experimental design", it refers to the careful planning and arrangement of various components, factors, and variables within an experiment to ensure valid and reliable results. Therefore, the etymology of "experimental design" reflects the combination of the words "experimentum" and "designare", representing the methodical structure and organization of an experiment to achieve specific objectives.
