This document contains data and statistical analysis of time (waktu) for different methods (metode). There were 12 total data points across 4 methods. An ANOVA and post hoc tests found a significant effect of method on time. Specifically, method 4 took significantly longer than methods 1-3, with means of 22, 8, 12, and 10 minutes respectively.
