Does the outliers or extreme value of sample impact on confidence interval range?
5 answers
Outliers or extreme values in a sample can indeed impact the range of a confidence interval. Outliers, although often considered for removal due to their potential to bias results, can actually contain valuable information about the data set. In the context of extreme values, their identification is crucial for accurate statistical analyses, especially when determining confidence intervals. The presence of outliers can distort the estimation of parameters and affect the precision of confidence intervals, emphasizing the need for careful consideration when handling extreme values in data analysis. Properly addressing outliers and extreme values is essential for ensuring the reliability and accuracy of confidence intervals in statistical inference.
