b. Student Perception of Teacher Performance Data
Students’ Perceptions variable on the Teachers Performance was obtained via questionnaire which consists of 21 question items
with number of respondents were 96 students. There are 4 alternative answers where the highest score was 4 and lowest score was 1. Based
on the analysis of the Students perceptions on Teacher Performance variable using SPSS Statistics, then can be obtained the highest score
was 69 and lowest score was 44, with the Mean M 55.791, Median Me 56, mode Mo 58 and the standard deviation SD 6.040.
To develop students perception frequency distribution of Teacher Performance performed the steps as follows:
1. Calculate the number Total of Interval class k
= 1 + 3.3 log n = 1 + 3.3 log 96
= 7.541 rounded to 8 2. Calculate Data Range
Number of Class Interval k = highest
– lowest data = 69
– 44 = 25
3. Calculate the length of the class Total of interval Class k

Variable categorization of Student Perceptions about T
eachers’ Performance was using criterion ideal score. The calculation is as follows:

Performance of Teachers are classified into 4 categories of variable trend that is very good, very good, very less, and less. As for the
designation of the Student Perception of the tendency of Teacher Performance is based on 4 categories with the following conditions

The table above shows that there is a very good category of 44 45.833, of Good category was 35 36.458, the less category 14
14.833, and the very less category was 3 3.125. It can be concluded that the variable Students Perceptions on the Teachers
Performance was included in the category of very good that was 45.833.
