3. What does the ‘head()’ function in Pandas do?
Ans. Displays the top rows of a DataFrame.
4. What does a Scatter Plot visualize?

Ans. Distribution of numerical data.
5. Which canvas in the AI project framework focuses on the technology used?
Ans. ‘Who’ canvas.

6. What is the primary purpose of the ‘Why’ canvas in AI project management?
Ans. Identifying project objectives.
7. In statistics, what does the term ‘mean’ refer to?

Ans. Average of a dataset.
8. What is the primary use of a Histogram?

E. Short answer type question.
1. What is the ‘Define’ phase in the AI project framework?

Ans. The ‘Define’ phase involves clarifying the project objectives, scope, and understanding stakeholder
requirements.
2. What does the ‘When’ canvas in AI project management address?
Ans. The ‘When’ canvas focuses on project timelines, milestones, and the scheduling of tasks during the AI
project lifecycle.

3. Why is data visualization crucial in Data Science?
Ans. Data visualization helps communicate complex insights clearly, making it easier for stakeholders to
understand and make informed decisions.
4. What is an outlier in data, and why is it important to identify them during data visualization?
Ans. An outlier is an unusually extreme data point, and it’s crucial to identify them as they can distort statistical
analyses and machine learning models.
5. How can you handle empty values in a dataset, and why is it necessary to address them before training
an AI model?

Ans. Empty values can be deleted or filled, and addressing them is essential to prevent inaccurate predictions
and biased outcomes in AI models.
6. In Data Science, what does the term ‘feature’ refer to?
Ans. A ‘feature’ is a measurable property or characteristic of data used to train machine learning models and
make predictions.

7. How does the ‘Where’ canvas contribute to AI project planning?
Ans. The ‘Where’ canvas defines the physical and virtual locations where the project activities will be carried
out, ensuring a structured work environment.
8. What is the primary purpose of the ‘Why’ canvas in AI project management?
Ans. The ‘Why’ canvas helps identify and define the overarching goals and objectives of the AI project, aligning
the team with a clear sense of purpose.
