Hi, everyone~ I have some data originally designed for ANOVA. Unlike general process, the factor and the number of levels were decided before gathering data. The replication was made as well. My question is what if t-test says these two data set is different? Is there any other methods to check the similarity between replication? Many thanks... best regard, ~~~~~~~~~~~~~~~~~ Yongkyu Shin Office Water Resource CSUS Civil Eng. ~~~~~~~~~~~~~~~~~ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
