In order to get the calculation of T-test, there are several steps to be taken; determining Mean, Standard Deviation and Standard Error from each variable.
The following steps describe as follows: 1.
Determining Mean of Variable X: ∑
2. Determining Mean of Variable Y:
∑
3. Determining Deviation Standard of Score of Variable X:
√ ∑
√ √
4. Determining Deviation Standard of Score of Variable Y:
√ ∑

8. Determining t

with formula:
9. Determining Degrees of Freedom df, with formula:
The value of df 58 at the degrees of significance 1 or t
table
is 2.392. From the result of statistical calculation above, it can be seen that the value
of t or t
test
is 4.01 and the degree of freedom df was 58. The value of t in the degree of freedom of 58 and at the degree of significance 1 or t
table
of df 58 with ɑ =1 is 2.392.
3. Interview Result
Regarding to the students’ perception toward English songs from YouTube, all of students felt motivated while mastering vocabulary used
English songs from YouTube because it helped them easier to master vocabulary. They agreed when they easily could remember the vocabulary.

H : There is no significant difference between students’ achievement
in vocabulary mastery which is taught using English songs from YouTube and without English songs from YouTube.
And then, the criteria used as follows: 1. If t-test t
o
t-table t
t
in significant degree of 0.01, Ho null hypothesis is rejected.
2. If t-test t
o
t-table t
t
in significant degree of 0.01, Ho null hypothesis is accepted.
From the result of the statistical calculation, it shows that the value of t
t
with df 58 in the significance 1 is 2.392, while the value of the t
o
is 4.01. Since score is higher than
score obtain from the result of calculating, so the alternative hypothesis
is accepted and the null hypothesis is rejected.
C. Interpretation of Data
Based on the analysis of the data, it was found that there was a significant difference between students’ achievement on vocabulary mastery in experimental
class which used English songs from YouTube and the control class which did
not. It can be seen from the students’ pre-test and post-test score. The pre-test average score of students in experimental class was 57.16, and the post-test
average score of students in experimental class was 75.33. Meanwhile, the pre-test score in control class was 61.5, and the post-test average score in control class
was 70.66 Therefore, it can be concluded that English songs from YouTube is

o
t-table t
table
in significance 0.01 or 1. Thus, the value of the t
o
was 4.01, while the value of t
t
with df 58 in the significance 1 was 2.392. Therefore, t
o
score was higher than t
table
score obtain from the result of calculating, so the alternative hypothesis H
a
