The lowest 48
The number of the students who got 75 or more 0 Source: The Result of Students’ Experimental Class Pre-Test on July 18th, 2016.
Based on the table above, the researcher measured the class interval using Sugiono’s formula as follows:
R = the highest score – the lowest score
= 72-48
= 24
K = 1+3.3 log n
= 1+4.363 = 5.363
= 6
P = R
K
= 24 6

Based on the table of frequency distribution above, it can be inferred that there were only 5 (23.81%) students who passed from 75 as the Minimum Mastery Criteria (MMC) or high category. Therefore, it can be inferred that the students’ report writing skill is low.
b. The Result of the Students’ Post-Test
The researcher conducted post-test in the last meeting of the research in order to compare the students’ report writing skill before and after a treatment was given. And the data of post-test score at the control class as follows:
