Question

can someone explain this chart to me? What is is saying and what do the numbers mean?

Source	SS	df	MS	F	p
Between	114.3111	2	57.1556	19.74
Within	121.6	42	2.8952
Total	235.9111	44

Answer 1

ANOVA table will give you information about the variability between groups and within groups. The table will give you all of the formulae.

Source	SS	DF	MS	F
Treatments	SST	k-1	SST/(k-1)	MST/MSE
Error	SSE	N-k	SSE/(N-k)
Total (Corrected)	SS	N-1

SST means Sum of squares of treatments, SSE means Sum of squares of errors

DFT which is k-1 means degrees of freedom for treatment, DFE which is N-k means Degrees of freedom for errors.
