EVALUATION REPORT — ATTEMPT 1 — REVISION NEEDED
Overall Evaluator Comments
EVALUATOR COMMENTS
Your work does a good job when discussing the lack of insight about other variables impacting attrition as a limitation of the linear regression analysis. You also provide a logical justification to support a linear regression analysis as an appropriate technique to determine the correlation between the two variables. More feedback is provided below to assist with revisions.
A. Data-Driven Decision
Competent
Competent The business question described is derived from the scenario and is consistent with the application of linear regression analysis.
· There are no comments on this aspect.
B1. Description of Relevant Data
Approaching Competence
Approaching Competence, the description does not accurately address the relevant data characteristics of the linear regression analysis, or 1 or more of the given elements are not included.
EVALUATOR COMMENTS: ATTEMPT 1
Participation rates are accurately described as the explanatory variable (independent variable). However, nurse attrition is incorrectly identified as the independent variable.
B2. Graphical Display
Competent
Competent The graphical display of the data uses a scatter plot or line chart to accurately represent the data, including each of the given elements.
· There are no comments on this aspect.
C1. Analysis Output and Calculations
Approaching Competence
Approaching Competence. The linear regression analysis output or calculations provided contain 1 or more inaccuracies.
EVALUATOR COMMENTS: ATTEMPT 1
A graphical display is clearly provided. However, a graphical display does not provide sufficient output from a linear regression analysis. Please provide appropriate output for a linear regression analysis, which typically includes a regression summary.
C2. Analysis Technique Justification
Competent
Competent The justification of linear regression analysis logically explains why it is the appropriate technique to predict the dependent variable and is supported with relevant details from the scenario.
· There are no comments for this aspect.
D1. Null Hypothesis
Competent
Competent The null hypothesis provided is accurately stated for the linear regression analysis and is relevant to the scenario.
· There are no comments on this aspect.
D2a. Goodness of Fit
Approaching Competence
Approaching Competence, the discussion of goodness of fit is not supported with the appropriate test statistic from the linear regression analysis output, or the interpretation of the test statistic is inaccurate.
EVALUATOR COMMENTS: ATTEMPT 1
The goodness of fit is clearly discussed for the r-square value 0.554. However, an output summary could not be located to validate the discussion.
D2b. Independent Variable(s) Significance
Approaching Competence
Approaching Competence, the discussion of the significance of the independent variable(s) is not logical or is not supported by the linear regression analysis results, or the associated interpretation of the comparison to the significance level is inaccurate.
EVALUATOR COMMENTS: ATTEMPT 1
A significant relationship is clearly discussed. However, the work lacks sufficient detail, which typically includes a comparison of the appropriate test statistic to the significance level, to support a determination of significance.
D2c. Linear Equation
Approaching Competence
Approaching Competence, the linear equation provided is not accurate, or the explanation does not logically address the purpose of the linear equation using analysis results.
EVALUATOR COMMENTS: ATTEMPT 1
A linear equation is clearly identified, and the work accurately describes using the equation to predict attrition rates. However, regression output could not be located to determine the accuracy of the linear equation.
D3. Limitation
Competent
Competent The discussion accurately identifies a limitation of the research and logically addresses how the limitation could affect a recommended course of action.
· There are no comments on this aspect.
D4. Recommend Course of Action
Approaching Competence
Approaching Competence, the recommended course of action is not logically aligned with the results of the linear regression analysis.
EVALUATOR COMMENTS: ATTEMPT 1
Promoting the plan is clearly recommended. However, appropriate output for a linear regression analysis could not be located, which makes it unclear whether the recommended course of action is aligned with the results.
E. Sources
Competent
Competent The submission includes in-text citations for sources that are properly quoted, paraphrased, or summarized and a reference list that accurately identifies the author, date, title, and source location as available.
· There are no comments on this aspect.
F. Professional Communication
Competent
Competent Content reflects attention to detail, is organized, and focuses on the main ideas as prescribed in the task or chosen by the candidate. Terminology is pertinent, is used correctly, and effectively conveys the intended meaning. Mechanics, usage, and grammar promote accurate interpretation and understanding.
· There are no comments on this aspect.
