Question: Two approaches to learning problem solving strategies were investigated. 36 graders were randomly assigned to one of the two approaches [a₁, a₂] & a control condition (a₃). The dependent variable is the number of solutions proposed. Do an analysis of variance for the following, with n = 10 in each of the three groups.

	a₁	a₂	a₃
Mean	14.7	11.2	12.2
Variance	6.46	4.18	10.62

a. Provide a source table.

	SS	df	MS	F	Significance (α = 0.05)
Group Error
Total
