CHAPTER IV RESEARCH FINDING AND DISCUSSION
A. Data Description
In order to know the result of the test, the writer provided the score of students which was gained from the test conducted in pre-test and pos-test in a table and in
order to make the result of the test clearer the writer also provided the comparison table to show the differences between students score in pre-test table and post-test
table. The following table is the table of students score in pre-test which known also
as the result of students’ speaking score before being taught using “Find Someone Who” game.

From the table above can be seen that the lowest score of pre-test was 33; meanwhile the highest score of pre-test was 71 and the mean score of pre-test was
47.36. In pre-test there are two highest frequencies of score which occurs four times: 33 and 50 and nine lowest frequencies of score which only occur once there
are: 34, 43, 46, 48, 49, 55, 61, 65, and 71. Furthermore, in order to find out the differences between students score, the writer showed
the result of students’ pos- test or the test which conducted after the students being taught using
“Find Someone Who” game in the following table:

From the table of post-test above can be seen that the lowest score of post-test was 33; whereas the highest score of post-test was 76 which indicates that there
are some improvement in the score of post-test. The mean score of pre-test was 59.32. In post-test the highest frequency of score which occurs four times is 65
and the lowest frequencies of score which only occur once there are: 33, 46, 53, 57, 67, 73 and 76.
B.
Data Analysis
The data which gained from pre-test and post-test will be calculated in order to find out the mean differences between the score from pre-test which taken before
the students were given the treatment using “Find Someone Who” game and the
score from post-test which taken after students were given the treatment using “Find Someone Who” game. The following table will show the average score that
occur between pre-test and post-test:

After finding out the differences between X

pre-test and X

post-test which will considers as data D, the next step is finding out the average score from
data D and in order to find out the mean of D ̅ the writer used the following
formula: ̅
=
∑
̅ = =
Furthermore, after the writer found the differences between score D and ̅ by
subtracting them; finally, the result of calculation process between D and ̅ will
be squared see Table 4.3 in order to find out the standard deviation of sample using the following formula:
√
∑ ̅
√ √

Moreover, after gaining the result of standard deviation from sample, the writer calculated the standard deviation from
̅ in order to gain the t-score from this study t
which calculated using the following formula:

Furthermore, the result of calculation process which has been elaborated above will show the degree of differences which is occur between X

and the degree of differences between X

and X

is 6.53. Finally, in order to complete the result of this study the writer made a
comparison from the score of t
based on dk derajat kebebasan or known also as degree of freedom df using the following formula:
dk = N – 1
dk = 25 – 1
dk = 24 In consequence, based on
t
table
dk = 24 at level significant 1 and 5 are: t

at significant level 1 = 2.797 t
table
at significant level 5 = 2.064 In consequence, the result was 2.064 6.53 2.797 and it showed that
