d. Parents Concern
Parents Concern data variable obtained through the now comprising 18 items of the 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 the Parents Concern variable by using a data-processing computer application, then obtained the
maximum score is 67 and the minimum score is 39, with a Mean value of M of 52.47, Median I in the amount of 53.00,
mode Mo in the amount of 50.00, and standard deviation SD of 6.60.
To compile the distribution frequency of Locus of Control is carried out the following steps:
84 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
= 67 – 39
= 28 c Calculate the length of the class
