4. Standardize formats
5. Filter out irrelevant data
6. Validate data accuracy
7. Normalize data if necessary

Right Answer:
A pivot table is a data processing tool that summarizes and analyzes data in a spreadsheet, like Excel. You use it by selecting your data range, then inserting a pivot table, and dragging fields into rows, columns, values, and filters to organize and summarize the data as needed.

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:
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:
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:
A BAPI (Business Application Programming Interface) is a standardized programming interface that allows external applications to interact with SAP systems, enabling data exchange and business process integration. A BADI (Business Add-In) is a type of enhancement technique that allows developers to add custom functionality to SAP applications without modifying the original code. The key difference is that BAPIs are used for external communication, while BADIs are used for internal enhancements within SAP.

Right Answer:
RTE manages port-based communication by using sender-receiver and client-server communication patterns. It defines ports for each software component, allowing them to exchange data through these ports. The RTE handles the mapping of data between components, ensuring that messages are sent and received correctly, while also managing the underlying transport mechanisms and synchronization.

Right Answer:
Sender-receiver communication is a one-to-one communication model where a sender transmits messages directly to a receiver, typically used for periodic data exchange. Client-server communication, on the other hand, involves a client requesting services or data from a server, which processes the request and sends back a response, often used for more complex interactions and service-oriented architectures.

Right Answer:
Ab Initio handles parallelism through two main types:

1. **Data Parallelism**: This involves splitting data into smaller chunks that can be processed simultaneously across multiple nodes or processes. Each node works on a different subset of the data.

2. **Component Parallelism**: This allows multiple instances of a component to run in parallel, enabling different operations or transformations to occur at the same time within the same graph.

Both types enhance performance and efficiency in data processing.

Right Answer:
A report in ABAP is a program that retrieves and displays data from the database in a structured format. The types of reports in ABAP are:

1. **Classical Reports**: These are basic reports that display data in a list format and allow simple user interactions.
2. **Interactive Reports**: These reports allow users to interact with the data, such as drilling down into details by clicking on specific entries.
3. **ALV Reports (ABAP List Viewer)**: These provide advanced features for displaying lists, including sorting, filtering, and exporting data.

Right Answer:
Sales and marketing are two related but distinct activities. Marketing involves promoting and creating awareness of a product or service to attract potential customers, while sales is the process of directly engaging with those customers to persuade them to purchase the product or service.
