This test is designed by our class four, and class five did it in November18th. The testing subjects are 41 juniors (39 girls and 2 boys), who major in the teaching English Department of Anqing Teachers College.

The examination paper contains one hundred multiple choice and one point a choice, so the total score is 100. The content of these items is from CET4, CET6 and TEM4 exam paper, which including many important grammars, like the use of article, preposition, verb and so on. It may seem to be easy in appearance, however, it costs too much efforts and devotions. The one hundred multiple choice were selected from 9 dormitories. Each dormitory should find out 50 items and then the final items were selected by study monitor. The test was taken in a big room205 within 40 minutes, with two study monitors and a teacher invigilated, which seems to be a little nervous. All in all, we all pass it smoothly. And after taking the examination, I felt to be a teacher and a student are not easy. Well, next, I will analyze this test results to you.

Part 2 Data presentation and analysis

In this part, I will report the test scores and provide some statistics to analyze several factors concerning with assessing the paper. Such as mean score, median, mode, range, standard deviation, test reliability, item difficulty level and item discrimination. Since the reliability is too difficult and complicated, I will analyze it in the end.

1. Basic Data

So, to begin with, let me analyze the basic data to you. Class five did a good job in this test. The central tendency is as follows: The mean score is 56.97561, media is 55, mode is 66. The variability is as follows: the range is 39, the standard deviation is 10.55578 and the CV is 18.5268%. The hole data are presented as follows:

Basic Data

CV：差异系数

Standard deviation：标准差

range：全距

And next is score distribution of the student:

Score Distribution

From the table and chart we can see that students’ score distribution is approximately around 40 and 80. It is concentrated and stable. The top score is 79 while the lowest score is 40.The whole trend is appeared as positive skewedness.

And then let us see the distribution of the option. The distribution of four option A, B, C, D is as follows. From the chart we can see that the four parts are almost equal. However, the option B is the highest one while the option C is the lowest one. Generally speaking, the options in this test are reasonable and advisable.

Option Distribution

And next let me analyze the advanced data to you.

4.Item Facility Value (FV)

Item facility value is a measure of the ease of a test item, which is important in test analyzing. It is between 0 and 1, the smaller it is, the more difficult the item will be. The reasonable facility value is between 0.3 and 0.7.

R

FV

N

( R is refers to No. of correct answers N is refers to No. of students )

And this examination’s every item facility value is as follows:
