Correct Answer
B. Machine learningExplanation
Machine learning is a method involved in data mining. It is a branch of artificial intelligence that focuses on developing algorithms and statistical models to enable computers to learn and make predictions or decisions without being explicitly programmed. In data mining, machine learning techniques are used to analyze large datasets, identify patterns, and extract valuable insights and knowledge. By utilizing algorithms, machine learning helps in discovering hidden patterns and relationships within the data, making it an essential method in the data mining process.Rate this question:

The data mining test assesses knowledge in one of these.
- A.
Data reduction
- B.
Housing
- C.
JavaScript
- D.
Database
Correct Answer
A. Data reductionExplanation
The correct answer is data reduction because data mining involves analyzing large amounts of data to discover patterns and relationships. Data reduction is a technique used in data mining to reduce the size and complexity of the data set by removing irrelevant or redundant information. This helps in improving the efficiency and effectiveness of the data mining process by focusing on the most relevant data.Rate this question:

The application questions test what kind of skills?
- A.
Management
- B.
Absolute
- C.
Practical
- D.
Writing
Correct Answer
C. PracticalExplanation
The application questions test practical skills. This means that the questions assess the ability to apply knowledge and skills in real-life situations, rather than just theoretical understanding. Practical skills often involve problem-solving, critical thinking, and the ability to use knowledge in practical settings. These skills are important in many fields and professions, as they demonstrate the ability to effectively apply knowledge and solve problems in real-world scenarios.Rate this question:
