The Application of Descriptive Statistical Analysis of Foreign Language Teaching and Testing

In the traditional way of language testing, teachers usually analyze the scores by calculating the mean and classifying point segments. Though easy to operate, the method of mean calculation is susceptible to extreme data and the classification of point segments cannot tell the distribution of scores when they are abnormally distributed, resulting in the unavailability of positive feedback on teaching from the test. Therefore, this paper proposes the use of Descriptive Statistical Analysis and the Combination of Measures of Central Tendency, Divergence Tendency and Standard Score, which will find out valuable information to enhance the teaching quality.
