a Highest Group All respondents that have a score as many as the mean score plus
one standard deviation above M + 1SD. b Middle Group
All respondents who had the mean score minus 1 standard deviation and mean score plus one standard deviation between
M –1SD to M+1SD.
c Lowest Group All respondents who had scores lower than the mean score minus 1
standard deviation above M + 1SD Suharsimi, 2006:264
Mean ideal Mi and Standard Deviation ideal SDI is obtained by
the following formula: Mean ideal

Standard Deviation ideal =

= M + 1SD = 30 + 6
= 36 Middle Group
= M - 1SD up to M + 1SD = 30 - 6 up to 30 + 6
= 24 up to 36
Lowest Group = M - 1SD
= 30 - 6 = 24
Based on these empulations, it can be made frequency distribution tendency of moving class implementation as follows:

From the table above can be seen that in the tendency of moving class Implementation X1 there are 11 students 16.2 in the high
category, 57 students 83.8 in the fair category, and no students 0 in the low category.

is used the questionnaire consisting of 15 items using a Likert scale questions
consisting of 4 alternative answers, the highest score was 4 and the lowest score is 1. The highest score that can be obtained is 60 4 15 and the
lowest score is 15 1 15. In this study, the variable X

obtained the minimum score of 29.00 and the maximum score was 56.00. The mean at
the amount of 39.53, the middle value median is 40, the value that is often appeared mode is 40 and the standard deviation is 5.76.
To construct the frequency distribution of Accounting Classrooms Facilities Variable, done the following steps:

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 + 3.3 1.832508913
= 7.047279412 rounded to 7. 2 Determine the Range
Range = maximum score – minimum score
= 56 - 29 = 27 3 Determine the length of class interval
Length of class interval = = = 3.857 rounded to 4.
