Then the data was statistically processed to test for normality using the Lilifours test at a significant level of 0.05α. Based on the analysis of the normality test data, X produces Lcount of 0.212 and Ltable 0.258, which means Lcount <Ltable. while variable Y produces Lcount of 0.202 and Ltable of 0.258. This means Lcount <Ltable. Based on statistical data analysis, the data is normally distributed. Based on the -t distribution test, which is 2.384 > 1.833 Tcount> Ttable data.
