Based on t-test calculation obtained  =  and (58) = 1,67193 which mean (58) it can be concluded that the creativity of low students has more influence on learning outcomes. (2) Thereof and , with  on the significance level 5%, df:  and . Based on t-test calculation obtained  = dan (58) = 1,67193 that means (60) it can be concluded that high reasoning ability has more influence on learning outcomes. (3)Thereof and , with  on the significance level 5%, df:  and . Based on the LSD test and t-test the results obtained are low student creativity combined with high reasoning ability influence on learning outcomes]]>
