Right Answer:
Classification analysis is a data analysis technique used to categorize data into predefined classes or groups. It works by using algorithms to learn from a training dataset, where the outcomes are known, and then applying this learned model to classify new, unseen data based on its features. Common algorithms include decision trees, logistic regression, and support vector machines.

Right Answer:
A hypothesis is a specific, testable prediction about the relationship between two or more variables. To test a hypothesis, you can use the following steps:

1. **Formulate the Hypothesis**: Clearly define the null hypothesis (no effect or relationship) and the alternative hypothesis (there is an effect or relationship).
2. **Collect Data**: Gather relevant data through experiments, surveys, or observational studies.
3. **Analyze Data**: Use statistical methods to analyze the data and determine if there is enough evidence to reject the null hypothesis.
4. **Draw Conclusions**: Based on the analysis, conclude whether the hypothesis is supported or not, and report the findings.

Right Answer:
Descriptive statistics summarize and describe the main features of a dataset, using measures like mean, median, mode, and standard deviation. Inferential statistics use sample data to make predictions or inferences about a larger population, often employing techniques like hypothesis testing and confidence intervals.

Right Answer:
Clustering in data analysis is the process of grouping similar data points together based on their characteristics, without prior labels. It is an unsupervised learning technique. In contrast, classification involves assigning predefined labels to data points based on their features, using a supervised learning approach.

Right Answer:
Data normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It involves structuring the data into tables and defining relationships between them. Normalization is important because it helps eliminate duplicate data, ensures data consistency, and makes it easier to maintain and update the database.

Right Answer:
GET is used to retrieve data from a server, POST is used to send data to a server to create a resource, PUT is used to update an existing resource on the server, and DELETE is used to remove a resource from the server.

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

Right Answer:
The different types of APIs are:

1. **Open APIs (Public APIs)** - Available to developers and third parties.
2. **Internal APIs (Private APIs)** - Used within an organization.
3. **Partner APIs** - Shared with specific business partners.
4. **Composite APIs** - Combine multiple endpoints into a single call.
5. **Web APIs** - Accessible over the internet using HTTP/HTTPS.

Right Answer:
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.

Right Answer:
An API Gateway acts as a single entry point for clients to access multiple microservices, handling requests, routing them to the appropriate services, managing authentication, rate limiting, and aggregating responses.

Right Answer:
**Benefits:** Faster time to market, reduced risk, improved quality, faster feedback, happier teams.

* **Clear Sprint Goals:** Define specific, measurable, achievable, relevant, and time-bound (SMART) goals for each iteration.
* **Daily Stand-ups:** Facilitate short, focused daily meetings to identify roadblocks and coordinate efforts.
* **Sprint Backlog Management:** Keep the sprint backlog refined, prioritized, and realistic based on team capacity.
* **Timeboxing:** Adhere to time limits for meetings and tasks to prevent scope creep and maintain momentum.
* **Focus on Value:** Prioritize tasks that deliver the most business value within the iteration.
* **Remove Impediments:** Proactively identify and resolve obstacles that hinder the team's progress.
* **Limit Work in Progress (WIP):** Encourage the team to focus on completing tasks before starting new ones.
* **Continuous Feedback:** Regularly review progress, gather feedback, and adapt plans as needed.
* **Defined "Definition of Done":** Ensure a clear understanding of what it means for a task to be considered complete.
* **Team Collaboration & Communication:** Foster open and effective communication and collaboration within the team.

Right Answer:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."

Right Answer:
Cross-functional teams in Agile are important because they bring together all the necessary skills to complete work without dependencies on other teams. This leads to faster delivery, better problem-solving, and increased innovation. To foster collaboration, encourage open communication, shared understanding of goals, mutual respect, and a focus on collective ownership.

Right Answer:
Success in Agile is measured by:

* **Output:** Delivering valuable, working software frequently; achieving the product vision; meeting business goals; customer satisfaction; and predictability (consistent delivery).
* **Team Health:** Team morale; continuous improvement (velocity trends, retrospectives leading to action); collaboration; self-organization; and sustainable pace.
