79 Table 20. Determination of Locus of Control Internal and
External
Based on the above formula and the calculations and results on appendix page 169, then retrieved 17 students have Internal
Locus of Control type, 13 students include the External Locus of Control, and 43 students not classified or not include the Locus
of Internal and external Control.
c. Student Perceptions of Teacher Teaching Methods
The data variable perceptions of students in the teachers Teaching methods are obtained through the now,
which consists of 19 items statement with amount 63 respondents students. There are four alternative answers where
the highest score is four and lowest score is one. Based on the data analysis of the variable perceptions of students on the
teachers teaching methods by using a data-processing computer application, then obtained the maximum score is 65
and minimum score is 36, with a Mean value of M of 50.25, Median Me in the amount of 50.00, mode Mo in the amount
of 50.00, and standard deviation SD of 5.79.

80 To compile the distribution frequency of Locus of Control
is carried out the following steps: a Count the number of interval class
Total of interval class = 1 + 3,3 log n
= 1 + 3,3 log 63 = 6.93 rounded to 7
b Count the data range Data Range
= max score – min score
= 65 – 36
= 29 c Calculate the length of the class
