Abstract

The P value and confidence interval are the two most widely used statistical infer-ence tools. The American Statistical Association issued a warning statement on the use of the P value due to the misuse and abuse of the P value. There are some mistakes in understanding the P value and confidence interval which caused the wrong use of the P value. Furthermore, the readers may have never considered the relationship and difference between the P value and confidence interval. There-fore, this paper expects to introduce the definition of P value and confidence interval in a simple way, and we also hope to analyze the relationship and difference between the P value and confidence interval, to help readers understand the P value and confidence interval correctly. In addition, this paper also lists the misuse and arguments about the P value and confidence interval, to help readers use the P value and confidence interval correctly in the future.
