Categories of learning outcomes learner classroom experimentation and control classes are assigned based on the criteria of determining the interval score. It first determined the range of scores, with the formula:
Range Score class (r) = maximum score-Score minimum amount specified Then
class interval (k) 5. 5 the number of classes specified interval due to be employed 5 categories namely learning results is very high, high, medium, low, and very low.
after it was determined the length of the class intervals with the formula class Interval Length:
(p) = (Score Range class)/(number of class intervals)
Checking to get the deciding score with formula:
p. k = (1-r) X
Description:
p = class interval length
k = number of class intervals
r = range score class
X = score decisive
