Question

QUESTION 18

1. Suppose you classify participants into two groups – those who are procrastinators and those who are not. This would be which type of design?

   		a dependent variable design
   		a mixed variables design
   		a within-subjects design (related measures) design
   		a between-subjects (independent measures) design

2. What is the research hypothesis for the situation in which a researcher is predicting an inverse relationship between time on the job and motivation?

   		H1: r = 0.00
   		H1: r < 0.00
   		H1: r > 0.00
   		H1: r > 1.00

3. QUESTION 23

4. When we set an alpha level, we are doing which of the following?

   		Determining whether the test is one- or two-tailed
   		Determining the critical areas
   		Setting the hypotheses
   		Setting the risk of Type II error

Answer 1

Question 18

The answer would be a between subjects (independent measures) design. The experiment is not between related subjects so option a and c are incorrect. This is also not a mixed variable design so option b is also incorrect. So here option d is correct.

Question 19

researcher is predicting an inverse relationship between time on the job and motivation. so here r < 0.00. option b is correct here.

Question 23

When we set the alpha level, we determine the critical area. Option b is correct here.
