b. Locus of Control
Locus of Control variable data obtained through the now consisting of 27 items statement with the number of
respondents to 63 students. There are four alternative answers where the highest score is four and lowest score is one. Based
on the data analysis of Locus Control variable by using data processing applications, then can be obtained the maximum
score is 78 and the minimum score is 60 from, with the value of the Mean M is 68.34, Median Me is 69.00, mode Mo is
69.00 and standard deviation SD is 3.69. To compile the distribution frequency of Locus of Control
is carried out the following steps:
75 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
= 78 – 60
= 18 c Calculate the length of the class

Based on table 15 distribution of Locus of Control can be described a histogram as follows:

Distribution Internal and external Locus of Control variable are further
classified into three categories. There categories, i.e : high, enough and low. As for the tendency of Locus of Control
designation is based on 3 categories with the following conditions:

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.
