Kolmogorov-Smirnov & T-Test Analysis

The document contains the results of statistical tests performed on dataset DataSet3. It includes a one-sample Kolmogorov-Smirnov test to compare the normality of the variable Waktu_reaksi to a normal distribution, finding no significant difference. It also includes an independent samples t-test to compare the mean of Waktu_reaksi between two groups (Pagi and Malam), finding no significant difference between the groups. The dataset contained 13 observations and the tests found the data to be normally distributed and no significant difference in the variable between the two time periods.
