71 addition, it also presented a table of frequency distribution and
histogram of the frequency of each variable. The following data processing has been done with the help of a data processing
application program.
a. Accounting Learning Achievement
Based on the Achievement of learning acquired through Accounting documentation in the form of the average value of
three times daily tests, the value of the midterm and final exam in SMA Negeri 2 Sleman student class of XI IPS academic
year 20162017, the maximum value is 8,40 and the minimum value is 5.90. Further analysis is performed using data
processing application programs obtained mean is 7.05, median is 6.90, mode is 6.70 and standard deviation is 0.564.
The number of class intervals is rounded 6.9 to 7. Range data 8.40
– 5.90 = 2.5, whereas the length of the class derived from range data divided by the number of class intervals 2.57
= 0.35. Rounded up to 4. As for the learning achievements of accounting frequency distribution can be seen in the following
table:

Based on the table 13 distributions of variable Accounting Learning Achievement frequency, the histogram can be described
as follows:

73 Identification of a tendency to TUNTAS or TIDAK TUNTAS of
Accounting Learning Achievement in this study uses the value of the Kriteria Ketuntasan Minimum KKM in accordance with
the rules of a given school. If the learning achieved ≥ 75,
students expressed satisfaction study or competent, otherwise if the
learning achieved ≤ 75, students found not competent or not completely. Based on the above data, created a category of the
tendency as follows: Table 14. Categories of Accounting Learning Achievement
