c. Learning Motivation
Learning Motivation variable data was obtained via the questionnaire which consists of 18 item questions with number of
respondents were 96 students. There are 4 alternative answers where the highest score was 4 and the lowest score 1. Based on the Learning
Motivation variables data analysis using SPSS Statistics, it can be obtained the highest score 65 and lowest score 36, with Mean M
49.833, median Me 50, the mode Mo 52, and the standard deviation SD of 6.199.
To compile the distribution frequency of Learning Motivation the following steps was done:
1. Calculate the total of interval classes Total of interval classes k
= 1 + 3.3 log n = 1 + 3.3 log 96
= 7.541 rounded to 8 2. Calculate the data range
Total of interval classes k = highest data
– lowest data
= 65 – 36 = 29
3. Calculate class length Total of interval classes k

= 3.625 rounded to 4 Table 14. Distribution of Learning Motivation distribution

Learning can be described as the following histogram:

of variable inclination that is very high, high, low, and very low. As for this inclination of the Learning motivation was based 4 category with the
following conditions Djemari Mardapi, 2008: 123 Table 15. Categories Learning Motivation Variables

Very Low Refers to the calculated categories of inclination, then the distribution
of Learning Motivation category can be shown in the following table.

The table above shows that the very high category was 46 47.917, high category was 34 35.417, lower category was 13 13,541, and the
category very low was 3 3,125. It can be concluded that the Learning Motivation variables included in the very high category was 47.917.
Based on the distribution of Learning Motivation variables frequency trend of above can be illustrated in the following Pie Chart
