QUESTION
Data Analysis Assignment Instructions
 
Directions:  Review the Houck, Kendall, Miller, Morrell, and Wiebe (2011) study and answer the following questions.
 

What are the independent or predictor variables included in Table 4 in the Houck et al. (2011) study?

 

What is the dependent variable being predicted in Table 4?

 

What type of analysis was conducted to predict the children and adolescents with ADHD self-concept scores from their behavior problem scores? Was this type of analysis appropriate? Provide a rationale for your answer.

 

What was used to determine the significance of the regression analysis? What were the results for the significant independent variable in this analysis?

 

What was the percentage of variance explained by the regression analysis presented in Table 4?

 

What are the independent or predictor variables included in Table 5 in the Houck et al. (2011) study?

 

What is the dependent variable being predicted in Table 5?

 

What independent variables were significant in predicting self-concept in Table 5? What were the results for the significant independent variables in this regression analysis?

 
Directions: Discuss the following correlational results from a current research article. Identify the strength (weak, moderate, or strong) of the relationships, the directions of the relationships (positive or negative), and significance of the relationships, assuming a level of significance set at α = 0.05.
 
Correlational Research Article: Dickson, V. V., Howe, A., Deal, J., & McCarthy, M. M. (2012). The relationships of work, self-care, and quality of life in a sample of older working adults with cardiovascular disease. Heart & Lung, 41(1), 5-14.
 
“The purpose of this study was to examine the self-care behaviors of adherence to medication, diet, exercise, and symptom monitoring of older workers with CVD [cardiovascular disease], and explore the relationships among job characteristics (job demands, job control, and workplace support), self-care, and quality of life” (Dickson et al., 2012, p. 7).
 

“People with higher levels of physical functioning reported better adherence [to medication, diet restrictions, exercise, and symptom monitoring] (r = 0.281, p = 0.002)” (Dickson et al., 2012, p. 9).

 

Strength of the relationship?

 

Direction of the relationship?

 

Significance of the relationship?

 

“Increased psychologic job demands were negatively associated with adherence (r = -0.31, p = 0.002)” (Dickson et al., 2012, p. 9).

 

Strength of the relationship?

 

Direction of the relationship?

 

Significance of the relationship?

 

“Better adherence was reported by those with increased job control (r = 0.244, p = 0.016)” (Dickson et al., 2012, p. 9).

 

Strength of the relationship?

 

Direction of the relationship?

 

Significance of the relationship?

 

“There was a significance correlation of the SCHDI [Self-Care of Heart Disease Index] maintenance scale and the Specific Adherence Survey (r = 0.641, p = 0.001)” (Dickson et al., 2012, p. 9).

 

Strength of the relationship?

 
 
 

Direction of the relationship?

 
 
 

Significance of the relationship?

 
 
 
Directions: Review the Kravits, McAllister-Black, Grant, and Kirk (2010) quasi-experimental study that focused on the effect of a psycho-educational intervention on stress reduction and prevention of burnout in nurses. Answer the following questions related to the analyses conducted to address the following hypothesis:
 
“1.1 The structure and content of this program will reduce EE [emotional exhaustion] and, as a result, reduce feelings of DP [depersonalization], and enhance feelings of PA [perceptions of personal accomplishment]” (Kravits et al., 2010, p. 132).
 
 
 

Kravits et al. (2010, p. 133) measured burnout using the Maslach Burnout Inventory—Human Services Survey (MBI-HSS). The MBI-HSS is a 22-item scale that was used to measure the three components of burnout: EE, DP, and PA. “Items are scaled from 0 to 6 with 0 = never and 6 = every day.” This is a Likert scale and these types of scale produce data that are usually considered at what level of measurement?

 

Nominal b. Ordinal c. Interval/ratio

 
 
 

The nurses were pretested and posttested using the subscales of EE, DP, and PA for measuring burnout. The pretest and posttest scores were examined for differences to determine if these scores changed following the implementation of the psycho-educational intervention. Are these groups independent or dependent? Provide a rationale for your answer.

 
 
 

What type of analysis test was used to determine differences in EE, DP, and PA for the nurses before and after the psycho-educational intervention? Was this analysis appropriate? Provide a rationale for your response.

 
 
 

What was the result of the comparison of the nurses’ EE scores pre- and postintervention? Was the result statistically significant?

 
 
 

What was the result of the comparison of the nurses’ DP scores pre- and postintervention? Was the result statistically significant?

 
 
 

What was the result of the comparison of the nurses’ PA scores pre- and postintervention? Was the result statistically significant?

 
 
 

Do these results support the hypothesis?
