What is the process of gathering and measuring information on variables of interest in an organized manner called?

  1. Data Analysis

  2. Data Collection

  3. Data Cleaning

  4. Data Visualization


Correct Option: B
Explanation:

Data collection is the process of gathering and measuring information on variables of interest in an organized manner, often using surveys, questionnaires, or observations.

Which of the following is NOT a common data cleaning technique?

  1. Data Transformation

  2. Data Imputation

  3. Data Standardization

  4. Data Aggregation


Correct Option: D
Explanation:

Data aggregation is a data analysis technique, not a data cleaning technique. Data cleaning techniques are used to remove errors and inconsistencies from data, while data aggregation techniques are used to combine multiple data points into a single value.

What is the process of examining data to identify patterns, trends, and relationships called?

  1. Data Analysis

  2. Data Collection

  3. Data Cleaning

  4. Data Visualization


Correct Option: A
Explanation:

Data analysis is the process of examining data to identify patterns, trends, and relationships. This can be done using a variety of statistical and mathematical techniques.

Which of the following is NOT a common data visualization technique?

  1. Bar Chart

  2. Pie Chart

  3. Scatter Plot

  4. Decision Tree


Correct Option: D
Explanation:

Decision Tree is a machine learning technique, not a data visualization technique. Data visualization techniques are used to represent data in a visual format, making it easier to understand and interpret.

What is the process of using statistical and mathematical techniques to extract meaningful insights from data called?

  1. Data Analysis

  2. Data Collection

  3. Data Cleaning

  4. Data Visualization


Correct Option: A
Explanation:

Data analysis is the process of using statistical and mathematical techniques to extract meaningful insights from data. This can be done using a variety of techniques, such as regression analysis, clustering, and decision trees.

Which of the following is NOT a common data analytics tool?

  1. Python

  2. R

  3. Tableau

  4. Power BI


Correct Option: D
Explanation:

Power BI is a business intelligence tool, not a data analytics tool. Data analytics tools are used to analyze data and extract insights, while business intelligence tools are used to create reports and dashboards.

What is the process of using data to make informed decisions called?

  1. Data-Driven Decision Making

  2. Data Analysis

  3. Data Visualization

  4. Data Mining


Correct Option: A
Explanation:

Data-driven decision making is the process of using data to make informed decisions. This involves collecting, analyzing, and interpreting data to identify patterns and trends that can be used to make better decisions.

Which of the following is NOT a common data analytics application?

  1. Fraud Detection

  2. Customer Segmentation

  3. Risk Assessment

  4. Natural Language Processing


Correct Option: D
Explanation:

Natural Language Processing is a field of computer science, not a data analytics application. Data analytics applications are used to analyze data and extract insights, while natural language processing applications are used to understand and generate human language.

What is the process of identifying and extracting valuable information from large amounts of data called?

  1. Data Mining

  2. Data Analysis

  3. Data Visualization

  4. Data Collection


Correct Option: A
Explanation:

Data mining is the process of identifying and extracting valuable information from large amounts of data. This can be done using a variety of techniques, such as association rule mining, clustering, and decision trees.

Which of the following is NOT a common data analytics technique?

  1. Regression Analysis

  2. Clustering

  3. Decision Trees

  4. Monte Carlo Simulation


Correct Option: D
Explanation:

Monte Carlo Simulation is a technique used in risk assessment and financial modeling, not a data analytics technique. Data analytics techniques are used to analyze data and extract insights, while Monte Carlo Simulation is used to generate random outcomes based on a set of assumptions.

What is the process of using data to predict future events or outcomes called?

  1. Predictive Analytics

  2. Data Analysis

  3. Data Visualization

  4. Data Mining


Correct Option: A
Explanation:
