Question

1. Suppose you were researching the effects of psychological skills training (PST), such as goal setting and imagery, on golf-putting performance (scored out of 10). Twenty-eight participants (14 male and 14 female) were recruited for the study. Seven male and seven female participants were randomly allocated to each of the two conditions. How would you describe this research design?

	a.	Two-way independent ANOVA
	b.	One-way repeated-measures ANOVA
	c.	Three-way mixed model ANOVA
	d.	None of the above are appropriate

2. How many independent variables are being measured in Question 1?

	a.	3
	b.	2
	c.	5
	d.	4

3. The variance explained by the experimental manipulation in Question 1 can be attributed to which of the following variables? Please select all that apply.

	a.	Gender
	b.	PST
	c.	Interaction between the two
	d.	None of the above

Answer 1

Answer a) Option A is correct

Explanation

A two-way ANOVA is, like a one-way ANOVA, a hypothesis-based test. However, in the two-way ANOVA each sample is defined in two ways, and resultingly put into two categorical groups. In this case the two-way ANOVA examines the effect of two factors (PST and gender) on a dependent variable – in this case golf-putting performance, and also examines whether the two factors affect each other to influence the continuous variable.

Answer c) Option B is correct

Explanation

There are two independent variables namely PST and Gender

Answer c) Option A, B, and C is correct

Explanation

In this case the two-way ANOVA examines the effect of two factors (PST and gender) on a dependent variable – in this case golf-putting performance, and also examines whether the two factors affect each other to influence the continuous variable.
