Experiment design

Experiment design is the process of planning how to test a hypothesis or answer a question systematically. It involves defining clear objectives, selecting variables to study, and establishing methods to collect and analyze data accurately. A good design ensures that results are reliable, valid, and unbiased by controlling factors that could influence the outcome. It also includes deciding on sample size, randomly assigning subjects or conditions, and determining procedures to minimize errors. Overall, a well-designed experiment provides trustworthy insights by systematically testing ideas while reducing the chances of misleading results.
