Experimental design in biology involves controlling variables to establish causal relationships between factors by comparing experimental and control groups.
Experimental design involves the systematic process of developing a research question, hypothesis, and conducting tests to establish causal relationships between variables. In an experiment, variables are controlled to minimize the influence of extraneous factors, with the experimental group undergoing the manipulation while the control group remains unchanged. By comparing the results of the experimental and control groups, researchers can determine the effect of the independent variable on the dependent variable.
