I think the formula for SSBc is incorrect. There appears to be a bar missing above xcol and I believe the values (squared differences) are scaled by the # of points in the column. The degrees of freedom formula, dfW, also suggests that there are an equal number of rows and columns rather than specifying the degrees of freedom in terms of the # of columns and the # of samples (n-c). Perhaps both could be specified? — Preceding unsigned comment added by JimHokanson ( talk • contribs) 15:21, 27 November 2023 (UTC)
The above sentence is horribly unscientific (it is found in the subsection "ANOVA for multiple factors"), even though a reference is given. Experience with what? Clearly no one has gained experience with all possible topics in which an ANOVA may be used. The text of the reference is not easily accessed, so it is not possible to check under what conditions this "experience" is applicable. I have marked it with a verification needed to signal that this claim needs to be modified. While it is relevant to the topic, the sentence as presented is false.
