This means that the influence of children's services on the growth of the GKJW Wiyung Surabaya church has a very influential relationship. With the correlation value R obtained at 0.696 with the influence on Y or R Square (coefficient of determination) = 0.484. This shows that the percentage contributing to the influence of X on Y. R Square = 0.484 implies that 48.4% of the contribution of X to Y. R Square ranges from 0 to 1. Note that the smaller the number of R Square, the weaker relationship X to Y. Because the data above the value of R Square is greater then it indicates that the stronger or increasing the relation of X to Y. So this can be said that the correlation value or the influence of the relationship on X and Y is good.
