Question

For each statement in the left column, choose the appropriate statistical support from the right column. Items in the right column may be used once, more than once, or not at all.

(All the numbers are fictional.)

	The smoking advertisement was rated higher among non-smokers than smokers...
	There was a significant difference among the cholesterol levels of participants in the medication group, the exercise group, and the control group...
	There was a positive relationship between the number of cigarettes a participant smoked per day and the perceived difficulty of quitting smoking...
	The proportion of degree-seeking and non degree-seeking graduate students in our sample matched the proportions in the College of Education...

A.	r(74) = .45, p < .001.
B.	F(392) = 9.71, p < .001
C.	t(66) = 3.35, p = .002
D.	χ 2(1) = 2.02, ns.

Answer 1

The smoking advertisement was rated higher among non-smokers than smokers...

Two means are compared here, hence independent t test

t(66) = 3.35, p = .002

There was a significant difference among the cholesterol levels of participants in the medication group, the exercise group, and the control group...

More than two groups are compared , hence

F(392) = 9.71, p < .001

There was a positive relationship between the number of cigarettes a participant smoked per day and the perceived difficulty of quitting smoking...

Here, the significance is correlation is tested,

r(74) = .45, p < .001

The proportion of degree-seeking and non degree-seeking graduate students in our sample matched the proportions in the College of Education...

Here, goodness of fit test is used:

χ 2(1) = 2.02, ns
