Experimental design refers to the plan or strategy that scientists use when conducting experiments. It helps them carefully organize the different aspects of an experiment, such as choosing the right variables to study, deciding how to measure those variables accurately, and determining how to compare different groups or conditions. Overall,
experimental design ensures that scientists can gather reliable and meaningful results from their experiments.

rigorous experimental design, and have been shown to have significant academic and social benefits, including long - term benefits.
Quantitative hypotheses, for instance, had to be «evaluated
using experimental designs in which individuals, entities, programs, or activities are assigned to different conditions with appropriate controls to evaluate the effects of the condition of interest through random assignment experiments, or other designs to the extent such designs contain within - condition or across - condition controls.»

about experimental design and interpretation and where data comes from.»
Challenges included overcoming
experimental design problems, such as creating a reliable method to monitor the miniscule energy fluctuations in their light source that would show up as interference in the measured signal.
