The symbols in the code refer to different components of an ANOVA test. "F1F1F1S1" represents between-group variation, "F1F1F10S1" represents within-group variation, "U1P12" represents the number of groups and sample size, and "S1S1P0" represents the size of error. The symbol "" in the second code does not represent any component of an ANOVA test, so it cannot correct for the number of groups and size of error.
