In psychological research, a common rule of thumb for achieving adequate power (typically aiming for 0.80 or 80% power to detect an effect if there is one) is to have at least 30 participants per group. This number is often considered a minimum to ensure a reasonable chance of detecting true effects, assuming a moderate effect size and conventional levels of statistical significance.
