A larger sample size reduces the impact of chance variation and increases the accuracy and reliability of the results. Having a larger sample size means that outliers and extreme values are less likely to skew the data, and the results are more representative of the population as a whole. Additionally, larger sample sizes allow for more statistical tests to be performed, increasing the complexity and accuracy of the analysis.
