: Processed primary Data by SPSS 20 Based on table above 9 question about service quality it can be seen
that all questions are valid, because the score of α 0.30, it means the data is valid and have positive correlation or the score corrected item
total correlation is 0.30, it means the data is valid. Measurement result is reliable if the coefficient α 0.60 Imam
Ghozali 2005: 42 from table above the value of Cronbach alpha more than 0.60, it means 9 questions of service quality have the reliability
value is good and feasible.
