Increasing the sample size from 20 to 100 participants increases statistical power, which means that the results are more likely to be statistically significant. This is because a larger sample size reduces the likelihood of random error and increases the precision of estimates. However, increasing the sample size does not guarantee practical significance, face validity, or reliability.
