What results from starting an analysis with flawed data?
Choose 2 answers.
正解：A、D
解説：
Starting an analysis with flawed data significantly undermines the effectiveness of data-driven decision making. One major consequence is that more time is spent managing data than analyzing data. Analysts must devote substantial effort to cleaning, validating, and correcting errors before meaningful analysis can occur, delaying insights and increasing costs.
Another critical result is that missing data tend to skew the results of the analysis. Incomplete data can distort averages, trends, and statistical relationships, leading to biased conclusions and unreliable decisions. This is especially problematic in predictive and inferential analytics, where assumptions about data completeness are essential.
Using spreadsheets or placing data in charts does not inherently result from flawed data, nor does it resolve data quality issues. While visualization can help identify errors, it is not a direct outcome of starting with flawed data.
Data-driven decision making emphasizes that poor-quality input leads to poor-quality output. Ensuring data accuracy and completeness before analysis is essential for producing valid insights. Therefore, the correct answers are B and D.

What is the purpose of linking strategy to performance assessment in an organization?
正解：D
解説：
Linking strategy to performance assessment helps an organization define where it needs or desires to be and measure progress toward that target. This connection is essential because it ensures that performance metrics are not selected in isolation, but instead support the mission, goals, and priorities of the organization. When strategy and assessment are aligned, managers can evaluate whether operational efforts are contributing to desired outcomes, identify gaps between current and expected performance, and make better-informed decisions about improvement. The other options do not reflect the main purpose. Increasing data collection may occur, but it is not the central reason for linking strategy to assessment. Reducing action plans is not a valid objective, and translating the mission only for team players is too narrow and inaccurate. Strategic performance assessment creates direction, accountability, and clarity across the organization. Therefore, the correct answer is that it provides a target of where an organization needs or desires to be.
質問 # 83
An electronics retailer was presented with in-store signage in two formats. Each branch of the store used the signage that matched its location. An analysis was performed to compare means on sales. Which type of variable do the sales represent?
正解：D
解説：
In this scenario, sales are the outcome being measured after different signage formats are used across store branches. Because sales depend on the conditions being studied, they are the dependent variable. The independent variable is the factor believed to influence the outcome, which here is the type of signage format.
When an analysis compares mean sales under different conditions, the variable being observed for change is the dependent variable. This distinction is fundamental in experimental and comparative analysis. Although the terms "target variable" and "criterion variable" can appear in some analytical contexts, the standard and most appropriate term here is dependent variable because the study is evaluating whether the signage format affects sales performance. The question asks which type of variable the sales represent, and the answer is the one that identifies sales as the measured response to the change in treatment. Therefore, sales are the dependent variable because they reflect the result of the differing signage conditions across store locations.
質問 # 84
A patient satisfaction survey was conducted at Family Practice A. The average rating of online telemedicine visits was 4.5 out of 5, while in-person visits received a 3.0 out of 5.
Which samples should be used to compare the ratings?
正解：D
解説：
To make a valid comparison in data-driven decision making, samples must becomparable and drawn from the same population, differing only in the factor being evaluated. In this case, the goal is to compare patient satisfaction between online telemedicine visits and in-person visits atFamily Practice A.
Usingonline Family Practice A telemedicine visits and in-person Family Practice A visitsensures that both samples come from the same organization, patient base, and survey methodology. This controls for external factors such as practice standards, demographics, and survey design, allowing differences in ratings to be attributed to the visit type rather than unrelated variables.
Comparing total visits to only one visit type introduces imbalance. Including other family practices introduces external variation and invalidates the comparison. Data-driven decision making stresses consistency and relevance in sample selection to ensure accurate conclusions.
Therefore, the correct answer isD, as it uses comparable samples that isolate the variable of interest.
質問 # 85
What does prevalence measure when studying disease frequency?
正解：C
解説：
Prevalence measures all existing cases of a disease within a population at a given point in time or over a specified period. It includes both newly diagnosed cases and pre-existing cases that are still present. This makes prevalence a measure of the total disease burden in the population rather than a measure of the rate at which new cases arise. In public health and epidemiology, prevalence is especially useful for understanding how widespread a condition is and for planning healthcare services, allocating resources, and evaluating community health needs. It differs from incidence, which focuses only on new cases occurring during a specified time period. Because the question asks what prevalence measures, the correct answer is the one that captures all current cases, not just past or new ones. It also does not refer to potential future cases, since prevalence is based on observed disease status. Therefore, the best answer is all existing cases of a disease.
