The data of vocabulary mastery were obtained from a test. The data was taken from 25 students as the sample of the research as below:

       Table 1. The data of vocabulary mastery

23	60
24	65
25	70
	1180

                                       

     From the data above, the highest score of the test is 70, and the lowest score is 30, the range is 40.       Then, from the computation of the data of the vocabulary mastery, it is acquired:

a.       Mean

       Mean    =      

             =          1180

                           25

                         =          47,2

After being computed, it can be seen that the mean of the data is 47,2.

b. Median

The median is 45. 

c. Mode

    The mode of the data is 45.
