Based on table 4.4 above shows the mean of 30 students is 76.33. The median score from the table is 75. And the mode score
is 75. The set of score constitute a population determine as variance score is 74.02. Standard deviation is a quantity calculated
to indicate the extent of deviation for a group as a whole and it is 8.604. Then the sum gained from the total score is 2290.

5 Based on the table 4.6 above, the result of the pre-test of the
controlled class shows that the highest score on pre-test was 80 and the lowest was 50 with average was 65. The writer do not give
treatment to the controlled class. The student of the controlled class taught by giving some list of vocabulary and they were asked to
memorize and to find the meaning of the word using dictionary. Then, the result of the controlled class showed that the highest
score on post-test was 85 and the lowest was 60 with average was 68.66. It can be seen that the average of the gained score of the
controlled class was about 5 points. The writer had to analyse the result of the data of controlled
class. The data was analysed using SPSS v.22 for windows by steps as follow: Analyze
– Description – Statistic – Frequency Statistic. The table is below:
Table 4.7 Data Description of Pre-test Result of Controlled Class
The table 4.7 shows that the mean of the 30 students is 65.67. The median score from the table is 65. The mode score is
60. The set of the score constitute a population determine as variance score is 58.161. Standard deviation is a quantity
calculated to indicate the extent of deviation for a group as a whole and it is 7.626. Then the sum gained from the total score is 1970.
