A 3rd party is marketing an application for financial institutions to use for credit scoring. This application is an example of what type of analytics?
Correct Answer:B
Explanation
Prescriptive analytics goes beyond describing what happened or predicting what might happen. It recommends specific actions to take. A credit scoring application tells financial institutions exactly what decision to make about applicants, making it prescriptive. Descriptive analytics would just show past credit patterns. Predictive analytics would forecast future defaults. Diagnostic analytics would explain why defaults occur, but wouldn't tell you what to do about it.
Based on the results of a recently completed analytics initiative, the Human Resource department for a major department store implemented a change to its hiring practice to address the attrition rates of its sales associates. The new policy stated that candidates applying for sales positions must possess at least 3 years of relevant sales experience to be considered. After implementing the change, attrition rates are 10% higher and management is frustrated. Which of the following could result in this outcome?
Correct Answer:D
Explanation
The change proposed is not aligned to company strategy, because it may not address the root cause of the attrition problem, or it may conflict with other organizational goals or values. For example, the change may reduce the pool of qualified candidates, increase the hiring costs, or lower the diversity or customer satisfaction of the sales team. The change may also ignore other factors that influence the attrition rates, such as compensation, training, feedback, or recognition. Therefore, the change may not achieve the desired outcome of reducing attrition, and may even worsen it. Reference:

When reviewing the results of their analysis, the team is determining if the data supports their hypothesis and can be presented to decision makers. They are reviewing measures of variation, sample size and statistical significance. They realize that the p-value of 0.02 is lower than the initial target. This clearly indicates the team can:
Correct Answer:C
Explanation
A p-value of 0.02 means there is only a 2 percent probability the observed results occurred by random chance. Since this is lower than the typical target of 0.05, it provides strong evidence against the null hypothesis. The team can confidently reject the null hypothesis and support their alternative hypothesis. The low p-value indicates their findings are statistically significant and reliable enough to present to decision makers.
What type of data model describes the highest level of relationship between entities and represents how a business perceives its information?
Correct Answer:A
Explanation
A conceptual data model operates at the highest abstraction level and shows how the business itself thinks about and organizes its information. It focuses on entities and their relationships without worrying about technical details. A logical model adds more structure and detail. A physical model describes how data is actually stored in databases. For understanding what information matters to the business, the conceptual model is the right answer.
The analytics team is struggling with which recommendation to make. Their challenge is that they have five good options and this indecision is stopping them from moving forward. To help the team finalize their recommendation, the BA professional on the team recommends they complete:
Correct Answer:D
Explanation
Acceptance and evaluation criteria are the techniques that the BA professional on the team should recommend they complete, because they are the standards or measures that are used to evaluate the suitability and value of each option. Acceptance and evaluation criteria can help the team compare the benefits, costs, risks, and impacts of each option, and determine which one best meets the needs and expectations of the stakeholders. Acceptance and evaluation criteria can also help the team communicate the rationale and evidence behind their recommendation, and ensure that the recommendation is aligned with the business goals and objectives.

After completing their data analysis, an analyst is drawing out the results, explaining the methods and processes used, and identifying any limitations or weaknesses in the data or methods applied. While performing these steps, which recommended practice would the analyst apply?
Correct Answer:B
Explanation
Understanding stakeholder communication needs is fundamental when presenting analysis results. Different audiences need different levels of technical detail and different types of insights. An analyst explaining methods, limitations, and weaknesses must tailor this information to what each stakeholder actually needs to hear and understand. This ensures the findings land effectively and support good decision making rather than confusing or overwhelming the audience with irrelevant details.
A data scientist is working with a team of upper level managers to develop a strategy for creating an enterprise analytics program. What critical success factor would help ensure the organization obtains the most value from its data?
Correct Answer:C
Explanation
Building an enterprise analytics program requires leadership that thinks analytically and creates an environment where data science can flourish. Technical tools and data alone won't work if managers view decisions through a non-analytical lens. When management embraces analytical thinking and supports data-driven culture, the organization extracts maximum value from its data investments. This cultural foundation determines whether an analytics program succeeds or sits unused.
