In this test panelists were asked to determine the level of favorite against the sweetness of 5 examples of candied nata de coco with the criteria of assessment suggests the following:
9 = very like
Panelists Calculate F = KT Example / KT panelists
Conclusion if the price F count is greater than the F table, meaning of candied sugar levels nata example, there are differences that affect significantly (significantly) on consumer balaca acceptance (panelists). If the calculated F value is smaller than the value of F table means the opposite
