B. Validity and Reliability.
In this study, validity testing was using statistic method of product moment Pearson, and reliability testing was using reliability coefficient
Cronbach Alpha.
1. Validity Test Result.
By using significant level α = 5 and N 30, so r
value
table is 0.3610. If rXY is more than r
value
, means that there is a real correlation between variables. The result of validity testing is summarized 4.6

Table 4.7 above, shows that alpha point of study instrument every item are greater than 0.60, thus can conclude that the instrument of
questionnaire is reliable, Cronbach’s Alpha of promotion, service quality and customer experiences is above 0.60 and categorize high reliability
according to table 3.3 category high and low reliable while reliability category for brand is sufficient.
