Finally, the last procedure is evaluation of the error which means to distinct which errors will be corrected so the learner, which made an error,
will not be stress of getting correction. To do the last step which is quantifying each percentage of error, the formula below is used:

P =
Note: P: Percentage;
f: Frequency of a type of error; n: Number of total errors occur.

CHAPTER IV RESEARCH FINDING AND INTERPRETATION
A. The Data Description
1. The Result of Test
The writer has given an essay writing test. There were 38 students on the class, but the writer only took 30 students as a sample. Actually the total
of the student was 46 and most of them did not attend the class. The test is an essay writing te
st about „Describing your idol’, which is guided by four question. So that the students need to make a paragraph based on the
insruction given. After conducting the test, the writer analyzed the data from the students’ test to find out the errors that students made in hisher answer by
circling each erroneous item. The result of this identification can be seen as the following table.

As the calculation above, the writer describes the examples and the causes why the errors occur as follow:
1. The Error of Omission =
29.8
2. The Error of Addition = 3. The Error of Selection =
4. The Error of Misordering =
