Highest Group = M + 1SD
= 37.5 + 7.5 = 45
Middle Group = M - 1SD up to M + 1SD
= 37.5 – 7.5 up to 37.5 + 7.5
= 30 up to 45 Lowest Group
= M - 1SD = 37.5
– 7.5 = 30
Based on these empulations, it can be made frequency distribution tendency of Accounting Classrooms Facilities as follows:

c. Variable of Students’ Learning Motivation in Accounting Learning
Y
Instrument of Students’ Learning Motivation in Accounting Learning variables Y is used the questionnaire consisting of 20 items, the highest
score was 4 and the lowest score is 1. The highest score that can be obtained is 80 4 20 and the lowest score is 20 1 20. In this study, the
variable Y obtained the minimum score of 46.00 and the maximum score was 75.00. The mean at the amount of 64.24, the middle value median is
65, the value that is often appeared mode is 58 and the standard deviation is 6,025.
To construct the frequency distribution of Students’ Learning

1 Determine the Number of Class Intervals To determine the number of class intervals, used the Sturges Rule
formula that the number of class intervals = 1 + 3.3 log n, where n is the number of research subjects at the amount of 68 respondents.
The number of class intervals = 1 + 3.3 log 68 = 1 + 6.047279412
= 7.047279412 rounded to 7. 2 Determine the Range
Range = maximum score – minimum score
= 75 - 46 = 29 3 Determine the length of class interval
Length of class interval = = = 4.142 rounded to 4.
