Your work here identifies a business question for the scenario and understands why the decision tree is a good path forward. Your analysis shows your understanding of possible limitations for the data element and the decision tree. Please see the comments in the rubric for more information about the aspects that require revision.

A. Business Problem Description

Competent

Competent The business question is accurately described, is relevant to the scenario, and is appropriate for decision tree analysis.

· There are no comments for this aspect.

Competent

Competent The relevant data values are accurately identified for the decision tree analysis, including each of the given elements.

· There are no comments for this aspect.

C1. Decision Tree Diagram

Approaching Competence

Approaching Competence, the decision tree diagram provided does not contain 1 or more of the given elements, or the decision tree diagram contains 1 or more inaccuracies.

EVALUATOR COMMENTS: ATTEMPT 1

The work includes a decision tree. However, 2 of the payoff values are incorrect, and one of the three expected values is incorrect.

C2. Analysis Technique Justification

Competent

Competent The justification of decision tree analysis logically explains why it is the appropriate analysis technique and is supported with relevant details from the scenario.

· There are no comments for this aspect.

D1. Probabilities and Demand

Approaching Competence

Approaching Competence, the explanation does not logically address both the role of probabilities and the role of demand for 1 or more of the branches of the decision tree analysis.

EVALUATOR COMMENTS: ATTEMPT 1

The work describes decision tree values. However, the role probabilities and demands play is not logically addressed.

D2. Expected Values

Approaching Competence

Approaching Competence, the explanation does not logically and accurately address 1 or more steps required to determine the value of 1 or more nodes based on payoffs.

EVALUATOR COMMENTS: ATTEMPT 1

The work describes expected values. However, not all steps in the calculation process are identified.

D3. Limitations

Competent

Competent The discussion logically addresses 1 limitation of the data elements and 1 limitation of the decision tree analysis.

· There are no comments for this aspect.

E. Recommend Course of Action

Approaching Competence

Approaching Competence, the recommended course of action is not logically supported by the results of the decision tree analysis or does not appropriately address the business question from part A.

EVALUATOR COMMENTS: ATTEMPT 1

The recommendation appears to be correct; however, the inaccuracies of the decision tree diagram may impact the recommended course of action.

F. 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 for this aspect.

G. 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.

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.
