Cronbach Alpha-Coefficient
Table III shows the results for Cronbach Alpha-Coefficient
value. From the table, it shows that alpha coefficient value for
three elements which are attractiveness, efficiency and
stimulation is higher than 0.7, the scales shows high
consistency. On the other hand, alpha coefficient value for
dependability is 0.64 which is near to 0.7. It indicated that
dependability is a little bit consistent. Based on the data, this
fact is logic and indicates that the scales used in the
questionnaire are consistent.
