Question

6) Using the copied portion of the Results section, use these values: (hint: MSE is a common notation for MS_error; also you might find it helps to work backward from the F value that is given)

	SS	df	MS	F	p
Request Type
error
total

For low Rational scorers,

donations differed significantly by request type, F(2, 55) = 3.35, p < .05,

η² = .109, MSE. 2.98. In planned comparisons based on Small et al.’s

findings (2007, Study 3), donations were higher when a personalized victim

appeared alone (M = $3.18, n =17) than when statistics were added to the

victim request (M = $2.00, n = 22, p = .04) or when statistics were presented

alone (M = $1.79, n = 19, p = .02). The latter two means did not differ.

Answer 1

n=total no. of observations=17+22+19=58

Source	SS	df	MS	F	p
Request Type	9.983*2=19.966	3-1=2	3.35*2.98=9.983	3.35	P(F>3.35|F~F2,55)=0.0424
Error	2.98*55=163.9	58-3=55	2.98
Total	20.1+163.9=184	58-1=57
