Section 1

Fundamentals of Data in AI

1. Why is high-quality data essential for AI models?

It improves model accuracy and reliability.

It ensures faster processing times.

It reduces the need for governance.

It eliminates the need for training AI models.

2. What is the primary role of labelled data in supervised learning?

To improve data storage efficiency.

To automate data cleaning processes.

To anonymise sensitive data.

To guide the AI model in making accurate predictions.

3. What is a key risk of using low-quality or biased data in AI projects?

Slower processing speeds.

Increased hardware requirements.

Reduced marketing effectiveness.

Unreliable or unfair AI outputs.

Section 2

Data Governance and Management

4. What is the primary goal of data governance in AI projects?

To ensure data is secure, accurate, and ethically managed.

To optimise network performance.

5. Which of the following best describes critical data?

Data that contains personal information only.

Data that is outdated but still stored.

Data that is essential for decision-making and AI training.

Data that is infrequently accessed.

6. What is the main purpose of data lineage in AI?

To compress data for storage.

To improve AI’s decision-making speed.

To identify the origin, transformations, and usage of data.

To track data ownership.

Section 3

Data Ethics and Compliance

7. Why is regulatory compliance critical in AI projects?

To prevent bias in AI models.
