Right Answer:
Agile is an iterative and incremental approach to project management that focuses on collaboration, flexibility, and customer satisfaction. Unlike traditional, sequential (waterfall) methods, Agile embraces change throughout the project lifecycle through short development cycles called sprints.

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:
To facilitate effective sprint retrospectives, I would:

1. **Set the Stage:** Create a safe and open environment where the team feels comfortable sharing.
2. **Gather Data:** Collect information about what went well, what didn't, and any challenges faced during the sprint.
3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

Right Answer:
* **Epic:** A large, high-level user story that is too big to complete in a single iteration. It's usually broken down into smaller user stories.
* **User Story:** A small, self-contained requirement that represents a valuable piece of functionality for the end-user. It follows the format: "As a [user type], I want [goal] so that [benefit]".
* **Task:** A small, actionable item that needs to be done to complete a user story. It's a technical breakdown of the work required by the development team.

10. Student's t-Distribution

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:
Outliers are data points that significantly differ from the rest of the dataset. They can skew results and affect statistical analyses. To handle outliers, you can:

1. Identify them using methods like the IQR (Interquartile Range) or Z-scores.
2. Remove them if they are errors or irrelevant.
3. Transform them using techniques like log transformation.
4. Use robust statistical methods that are less affected by outliers.
5. Analyze them separately if they provide valuable insights.

Right Answer:
Data analysis is the process of inspecting, cleaning, and modeling data to discover useful information, draw conclusions, and support decision-making. It is important because it helps organizations make informed decisions, identify trends, improve efficiency, and solve problems based on data-driven insights.

Right Answer:
Correlation is a statistical measure that indicates the extent to which two variables fluctuate together, while causation implies that one variable directly affects or causes a change in another variable.

Right Answer:

A pie chart is a circular graph used to show how a whole is divided into different parts. Each “slice” of the pie represents a category, and its size reflects that category’s proportion or percentage of the total.

It’s one of the simplest and most visual ways to display data — especially when comparing parts of a whole.

—

🎯 Key Features of a Pie Chart:

• The entire circle represents 100% of the data.

• Each slice represents a specific category or group.

• Larger slices mean higher values or proportions.

• Often color-coded and labeled for clarity.

—

🔍 How to Extract Insights from a Pie Chart:

1. Read the Title & Labels
 Start by understanding what the chart is showing — it could be market share, survey responses, budget breakdowns, etc.

2. Look at Slice Sizes
 Compare slice sizes to see which categories are biggest or smallest.
 The largest slice shows the most dominant group.

3. Check Percentages or Values
 If percentages or numbers are given, use them to understand how much each slice contributes to the whole.

4. Group Related Slices (if needed)
 Sometimes combining smaller slices can help identify trends (e.g., combining all “Other” categories).

5. Ask Questions Like:
 - Which category has the largest share?
 - Are any categories equal in size?
 - How balanced is the distribution?

Right Answer:

A scatter plot is a type of graph that helps you understand the relationship between two variables. Each dot on the plot represents one observation in your data — showing one value on the X-axis and another on the Y-axis.

By looking at the pattern of the dots, you can quickly see whether the two variables are related in any way.

Right Answer:

Mean, median, and mode are the three main measures of central tendency. They help you understand the “center” or most typical value in a set of numbers. While they all give insight into your data, each one works slightly differently and is useful in different situations.

🔹 Mean (Average)

• What it is: The sum of all values divided by the number of values.

• Formula: Mean = (Sum of all values) ÷ (Number of values)

• When to use: When you want the overall average, and your data doesn’t have extreme outliers.

📊 Example:
Data: 5, 10, 15
Mean = (5 + 10 + 15) ÷ 3 = 30 ÷ 3 = 10

✅ Interpretation: The average value in the dataset is 10.

🔹 Median (Middle Value)

• What it is: The middle value when all numbers are arranged in order.

• When to use: When your data has outliers or is skewed, and you want the true center.

📊 Example:
Data: 3, 7, 9, 12, 50
Sorted order → Middle value = 9
(Median is not affected by 50 being much larger.)

✅ Interpretation: Half the values are below 9 and half are above.

🔹 Mode (Most Frequent Value)

• What it is: The number that appears most often in the dataset.

• When to use: When you want to know which value occurs the most (especially for categorical data).

📊 Example:
Data: 2, 4, 4, 4, 6, 7
Mode = 4 (because it appears the most)

✅ Interpretation: The most common value in the dataset is 4.
