Question

Page 182 problem #18 A researcher believes nurses are absent from work more frequently when the score higher on a test of “psychological burnout.” These are the data: 1. Burnout (X): 2, 1, 2, 3, 4, 4, 7, 7, 8 Absences (Y): 4, 7, 6, 9, 6, 8, 7, 10, 11

Write an APA results summary.

Expert Solution

Step 1

The provided data are shown in the table below

Burnout (X)	Absences (Y)
2	4
1	7
2	6
3	9
4	6
4	8
7	7
7	10
8	11

Now we will calculate the correlation coefficient to determine whether there is strong / moderate relationship between Burnout and Absences OR whether nurses are absent from work more frequently when the score higher on a test of “psychological burnout.”

Also, the following calculations are needed to compute the correlation coefficient:

	X	Y	*XY**	X²	Y²
	2	4	8	4	16
	1	7	7	1	49
	2	6	12	4	36
	3	9	27	9	81
	4	6	24	16	36
	4	8	32	16	64
	7	7	49	49	49
	7	10	70	49	100
	8	11	88	64	121
Sum =	38	68	317	212	552
