Correct answer: A, D
Good data quality management plays a critical role in improving business decision-making by ensuring that data is accurate, complete, and reliable. One key benefit is that it ensures there are no missing data points, which helps maintain data completeness. Missing data can distort results, reduce analytical power, and lead to incorrect conclusions, especially in descriptive and inferential statistics. Another important benefit is that data quality management mitigates undetected errors from the data-entry process. Errors such as duplicate entries, incorrect values, or inconsistent formats can significantly bias analysis if left unnoticed. Through validation checks, cleaning procedures, and governance standards, organizations reduce the risk of flawed insights. While good data quality supports better analysis, it does not guarantee statistical significance, as significance depends on sample size, variability, and study design. Similarly, it does not necessarily make the statistical process faster; in fact, data cleaning can be time-consuming. However, it improves the accuracy and trustworthiness of outcomes. In data-driven decision making, high-quality data is essential because decisions are only as good as the data used to support them. Therefore, the correct answers are A and D.
Question 2
Amusement Park W is in Californi a. Amusement Park X is in Texas. A survey asks 1,000 people living in California if they prefer Amusement Park W or X. Which problem exists with this survey?
- AOption A:
Information bias
- BOption B:
Random error
- COption C:
Systematic error
- DOption D:
Measurement bias
Show answer and explanation
Correct answer: C
The primary problem with this survey is systematic error, which occurs when the data collection process consistently favors certain outcomes due to flawed design. In data-driven decision making, systematic error arises when a sampling method introduces bias that skews results in a predictable direction. In this scenario, surveying only people living in California creates a location-based bias. Respondents are far more likely to prefer Amusement Park W because it is geographically closer, more familiar, and more accessible than Amusement Park X in Texas. This bias does not occur randomly; instead, it systematically influences responses toward one option, making the results unreliable for comparing overall preferences between the two parks. Random error would involve unpredictable variation, which is not the issue here. Measurement bias relates to how questions are asked or measured, and information bias concerns inaccurate or misleading data reporting. The core issue is the non-representative sample, which violates the principle of unbiased data collection. Data-driven decision making emphasizes that valid conclusions require representative samples. Because the survey design inherently favors one outcome, the results cannot be generalized, making systematic error the correct answer.
