WebApparently a narrow confidence interval implies that there is a smaller chance of obtaining an observation within that interval, therefore, our accuracy is higher. Also a 95% confidence interval is narrower than a 99% confidence interval which is wider. The 99% confidence interval is more accurate than the 95%. WebThe confidence level also affects the confidence interval width. However, this factor is a methodology choice separate from your sample’s characteristics. If you increase the confidence level (e.g., 95% to 99%) while holding the sample size and variability constant, the confidence interval widens.
