After that, normality data test with Liliefors test with significant planed α = 0.05, and find the normality test of variable’s value was X, L0maks (0,114) < Ltable (0,242), normality test of variable Y, L0maks (0,147) < Ltable (0,242), with other word was normally of data distribution. Then continued to found r used product moment correlation analysis, if rresult > rtable so it was have significant reletionshio.
