The table above describes the result calculation of the gain score of the experiment class X and the control class Y in learning Irregular Plural Nouns.
Based on table above, it can be concluded that the total score of the experimental class
∑X is 361and the control class ∑y is 166.
Chart 4.1 The Pre Test, the Post Test, and the Gain Scores of
the Control Class and the Experimental Class
The diagram above describes the score of both classes in average level. It shows that the students’ achievement in teaching Irregular Plural Nouns by using
Drilling experimental class higher than using Grammar Translation Method control class.
From the table above, the writer calculated them based on the steps of t-test formula, as follows:
1. Determining Mean I with formula Mean Variable I =
