การวิเคราะห์ค่าระดับความคำเห็นของผู

An analysis of the level of the respondent's comments at the end of the close (Close Ended Questionaire) of Li Curt (Likert Scale) and division levels measured data using antonphak class (Interval Scale) divided into 5 points, minimum score level as is 1 point. 5 points by using a formula to calculate a wide range of antonphak layers as follows (manlika Bunnag, 2537 (1994))

from the formula antonphak = class width maximum score minimum points of story
-
= (5-1)/5
= 0.8

Analysis of the level of the comments of the respondents closed (Close Ended Questionaire) Lil Kurt (Likert's Scale) and the level of dividing the information, type interval class (Interval Scale) by the score is 5 points lower. Max is 1 and the maximum score is 5 points by using the following formula to calculate the width of the interval (Mallika Bunnag, 2537). based formula, the width of the class interval = highest score - lowest score. many layers = (5-1) / 5 = 0.8

Analysis of the level of the see of respondents closed end (Close Ended Questionaire) of Likert (Likert 's Scale) and food level measure data using type class interval. (Interval Scale) divided into 5 score level. The lowest score was 1 points.5 points. Using the formulae a wide range of interval class as follows (Mallika, Bunnag2537)

recipes from the width of the interval I = maximum points - the lowest score

= (number of layers 5-1) / 5
= 0.8
