Right Answer: The purpose of feature engineering in data analysis is to create, modify, or select variables (features) that improve the performance of machine learning models by making the data more relevant and informative for the analysis.
Right Answer: Regression analysis is a statistical method used to examine the relationship between one dependent variable and one or more independent variables. It is used to predict outcomes, identify trends, and understand the strength of relationships in data.
Right Answer: The different types of data distributions include:
1. Normal Distribution
2. Binomial Distribution
3. Poisson Distribution
4. Uniform Distribution
5. Exponential Distribution
6. Log-Normal Distribution
7. Geometric Distribution
8. Beta Distribution
9. Chi-Squared Distribution
10. Student's t-Distribution
Right Answer: A project charter is a formal document that outlines the objectives, scope, stakeholders, and overall framework of a project. It serves as an official authorization for the project to begin and provides a high-level overview of what the project aims to achieve.
Right Answer: The critical path in a schedule network diagram is the longest sequence of dependent tasks that determines the shortest time to complete a project. Any delay in the tasks on the critical path will directly impact the project's overall completion time.
Right Answer: In a difficult situation, I would first assess the problem to understand its root cause. Then, I would communicate openly with my team to gather input and brainstorm solutions. Prioritizing tasks, staying organized, and remaining calm are crucial. Finally, I would implement the chosen solution, monitor progress, and adjust as needed while keeping stakeholders informed.
Right Answer: Risk refers to potential events that may negatively impact a project in the future, while issues are current problems that are already affecting the project and need to be addressed.
Right Answer: Project management is the process of planning, executing, and overseeing a project to achieve specific goals within a defined timeline and budget. It involves coordinating resources, managing risks, and ensuring effective communication among stakeholders to deliver successful outcomes.
Right Answer: A product backlog is a prioritized list of features, bug fixes, tasks, and requirements needed to build a product. It's managed through regular refinement, prioritization, estimation, and updates based on feedback and changing business needs, often facilitated by the Product Owner.
* **Individuals and interactions** over processes and tools.
* **Working software** over comprehensive documentation.
* **Customer collaboration** over contract negotiation.
* **Responding to change** over following a plan.
That is, while the items on the right have value, we value the items on the left more.
Right Answer: I would assess the organization's context, choose a suitable scaling framework like SAFe or LeSS based on needs, implement it incrementally with training and coaching, focusing on value delivery, and continuously inspect and adapt the implementation based on feedback and results.
Right Answer: Scrum is an Agile framework for managing and completing complex projects.
Implementation involves:
1. **Roles:** Defining roles like Product Owner, Scrum Master, and Development Team.
2. **Sprints:** Working in short, time-boxed iterations (Sprints), typically 2-4 weeks.
3. **Artifacts:** Using artifacts like Product Backlog, Sprint Backlog, and Increment.
4. **Events:** Conducting events such as Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
5. **Continuous Improvement:** Regularly inspecting and adapting the process based on feedback.
Right Answer: * **Listen actively:** Understand their concerns and perspective.
* **Communicate clearly and frequently:** Keep them informed about progress and challenges.
* **Find common ground:** Focus on shared goals and objectives.
* **Be transparent:** Share data and evidence to support decisions.
* **Facilitate collaboration:** Encourage open dialogue and problem-solving.
* **Coach and mentor:** Help team members grow and improve.
* **Escalate when necessary:** Involve a Scrum Master or manager if the situation doesn't improve.
Right Answer: The advantages of using a cross-platform framework include:
1. **Code Reusability**: Write once, run on multiple platforms, reducing development time and effort.
2. **Cost Efficiency**: Lower development and maintenance costs since a single codebase serves multiple platforms.
3. **Faster Development**: Accelerated development process due to shared code and resources.
4. **Consistent User Experience**: Uniform look and feel across different devices and platforms.
5. **Access to a Wider Audience**: Reach users on various platforms (iOS, Android, etc.) without separate apps.
6. **Easier Updates**: Simplified updates and bug fixes since changes are made in one codebase.
