Explain in 1–2 sentences how an experiment must be written so that the participants can be randomly assigned.(2 points)

Answer 1

In order to facilitate random assignment of participants in an experiment, the experimental design must include a method for randomly allocating individuals to different groups, such as using random number generators or drawing lots, ensuring that each participant has an equal chance of being placed in any treatment or control condition. This approach minimizes biases and helps establish causal relationships by controlling for confounding variables.
