I incorporate A different ANOVA Edition w/ three groups decrease down to clarify that a 2-team problem is not the only ANOVA circumstance that could be understood for a regression; although the reg equation now appears to be like distinct--I was hoping to keep up a far more explicit parallel higher than. $\endgroup$
