4.
One of this is covered in data mining test.
Correct Answer
D. Data processing
Explanation
Data processing is one of the topics covered in a data mining test. It involves transforming raw data into meaningful information by performing various operations such as cleaning, organizing, analyzing, and summarizing the data. This process is essential in order to extract valuable insights and patterns from the data, which can then be used for decision-making and problem-solving purposes.
5.
Which of these is a method involved in data mining?
Correct Answer
B. Machine learning
Explanation
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.
6.
The computational process of discovering patterns in a form of large data sets using artificial intelligence, statistics etc is termed?
Correct Answer
C. Data mining
Explanation
Data mining is the correct answer because it refers to the computational process of discovering patterns in large data sets using techniques such as artificial intelligence and statistics. This process involves extracting useful information and knowledge from the data, which can then be used for various purposes such as decision-making, prediction, and optimization. Programming, collection, and data processing are related concepts but do not specifically refer to the process of discovering patterns in large data sets.
7.
The data mining test assesses knowledge in one of these.
Correct Answer
A. Data reduction
Explanation
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.
8.
How many application questions are in the data mining test?
Correct Answer
C. 20
Explanation
The correct answer is 20 because it is stated in the question that there are application questions in the data mining test, and the number of application questions is specifically mentioned as 20.
9.
A question type in the data mining test is the?
Correct Answer
B. Fill in the blank
Explanation
The question is asking about a specific type of question in the data mining test. The correct answer, "Fill in the blank," refers to a question format where the test-taker is required to provide the missing information in a given sentence or statement. This type of question is commonly used to assess the test-taker's understanding and knowledge of the subject matter.
10.
The application questions test what kind of skills?
Correct Answer
C. Practical
Explanation
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.
