55 Based on table 4.5, 20 Question about celebrity endorser, from the
table, it can be seen that all the question is valid, because the score of coefficient correlation
α 0,30, it means the data is valid and have the positive correlation or the score corrected item-total correlation is 0,30,
it means the valid Sugiono, 2008:126.
Measurement result is stated to be reliable if the coefficient α 0.60
Imam Ghozali,2009:42 from table 4.5, the value of Cronbach alpha more than 0,06, it means 10 question of celebrity endorser have
reliabilities value a good and feasible.
