| Abstract: | Uncertain degree is, the extent to measured value that can not be determined and the assessment of measured ture value in a certain range. From the teaching practice, the article is to introduce the assessment method of uncertain degree and proper application in specific experiments, and then to estimate it through statistical method, in order to improve students' ability to deal with data. |
