Question

Use SPSS for this Application Exercise:
A physician hypothesizes that more labor pain is related to more infant bonding. The table below contains data for mothers' labor pain (higher score indicates more pain) and the amount of hours spent bonding with their infant after birth. What can the physician conclude with an α of 0.01?

infant bonding	labor pain
1 4 7 5 4 2 6 8 5 4 2	8 7 2 4 3 6 5 3 3 5 7

a) What is the appropriate statistic?
---Select--- na Correlation Slope Chi-Square
Compute the statistic selected in a):  

b) Input the appropriate value(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

c) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
effect size =  ;    ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

There is a significant positive relationship between labor pains and infant bonding.

There is a significant negative relationship between labor pains and infant bonding.     

There is no significant relationship between labor pains and infant bonding.

NOTE: This problem can only be solved using SPSS since that is what the problem specifies.

Answer 1

a) What is the appropriate statistic?
Correlation
Compute the statistic selected in a): -0.798

b) Input the appropriate value(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value = 0.003 ; Decision: Reject H0

c) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
effect size = 0.637 ;   medium effect

d) Make an interpretation based on the results.

There is a significant negative relationship between labor pains and infant bonding.
