Detailed explanation-1: -In experimental research, random assignment is a way of placing participants from your sample into different treatment groups using randomization. With simple random assignment, every member of the sample has a known or equal chance of being placed in a control group or an experimental group.
Detailed explanation-2: -The ideal way to minimize the effects of confounding is to conduct a large randomized clinical trial so that each subject has an equal chance of being assigned to any of the treatment options.
Detailed explanation-3: -Counterbalancing is a technique used to control for sequencing effects (the two sequencing effects are order effects and carry-over effects). Sequencing effects are biasing effects that can occur when each participant must participate in each experimental treatment condition.
Detailed explanation-4: -Randomization in an experiment means random assignment of treatments. This way we can eliminate any possible biases that may arise in the experiment. Good. Randomization in an experiment is important because it minimizes bias responses.
