The finding arrived at conclusion that statistically there was a significant relationship between students’ imagination toward their writing skill of descriptive text at value r = 0,5199511838 it means significant and hypothesis is accepted, because rxy= 0,5199511838 >rtable(0,329) at level of significance 5% and rtable (0,424) at level of significance 1%. This data result indicated that students’ imagination has moderate correlation toward their writing skill of descriptive text with Fcount (regression) = 12,643 while Ftable for df 1 : 34 (quantifier = 1; denominator = 34) at level of significance 5% = 4,13, it means that Fcount>Ftable, so that there was functional relation that was significant between variable of students’ imagination and writing skill of descriptive text.
