Explanation:

The t-test is used to compare the means of two independent groups.

What is the purpose of factor analysis?

  1. To identify underlying patterns in a dataset

  2. To reduce the number of variables in a dataset

  3. To test hypotheses about relationships between variables

  4. To predict outcomes based on a set of independent variables


Correct Option: A
Explanation:

Factor analysis is a statistical technique used to identify underlying patterns or factors in a dataset.

Which data mining technique is commonly used to find associations between items in a dataset?

  1. Clustering

  2. Classification

  3. Association rule mining

  4. Regression analysis


Correct Option: C
Explanation:

Association rule mining is a data mining technique used to find associations between items in a dataset.

What is the main purpose of descriptive statistics?

  1. To summarize and organize data

  2. To test hypotheses about relationships between variables

  3. To predict outcomes based on a set of independent variables

  4. To identify underlying patterns in a dataset


Correct Option: A
Explanation:

Descriptive statistics are used to summarize and organize data in a meaningful way.

Which statistical test is used to determine if there is a significant relationship between two categorical variables?

  1. t-test

  2. ANOVA

  3. Chi-square test

  4. Regression analysis


Correct Option: C
Explanation:

The Chi-square test is used to determine if there is a significant relationship between two categorical variables.

What is the purpose of inferential statistics?

  1. To summarize and organize data

  2. To test hypotheses about relationships between variables

  3. To predict outcomes based on a set of independent variables

  4. To identify underlying patterns in a dataset


Correct Option: B
Explanation:

Inferential statistics are used to test hypotheses about relationships between variables.

Which data mining technique is commonly used to predict outcomes based on a set of independent variables?

  1. Clustering

  2. Classification

  3. Association rule mining

  4. Regression analysis


Correct Option: D
Explanation:

Regression analysis is a data mining technique used to predict outcomes based on a set of independent variables.

What is the main purpose of exploratory data analysis?

  1. To summarize and organize data

  2. To test hypotheses about relationships between variables

  3. To predict outcomes based on a set of independent variables

  4. To identify underlying patterns in a dataset


Correct Option: D
Explanation:

Exploratory data analysis is used to identify underlying patterns in a dataset.

Which statistical test is used to determine if there is a significant difference between the means of two dependent groups?

  1. t-test

  2. ANOVA

  3. Chi-square test

  4. Regression analysis


Correct Option: B
Explanation:

ANOVA is used to determine if there is a significant difference between the means of two or more dependent groups.

What is the purpose of confirmatory data analysis?

  1. To summarize and organize data

  2. To test hypotheses about relationships between variables

  3. To predict outcomes based on a set of independent variables

  4. To identify underlying patterns in a dataset


Correct Option: B
Explanation:

Confirmatory data analysis is used to test hypotheses about relationships between variables.

Which data mining technique is commonly used to find clusters of similar data points in a dataset?

  1. Clustering

  2. Classification

  3. Association rule mining

  4. Regression analysis


Correct Option: A
Explanation:

Clustering is a data mining technique used to find clusters of similar data points in a dataset.

What is the main purpose of data visualization?

  1. To summarize and organize data

  2. To test hypotheses about relationships between variables

  3. To predict outcomes based on a set of independent variables

  4. To communicate information effectively


Correct Option: D
Explanation:

Data visualization is used to communicate information effectively.

Which statistical test is used to determine if there is a significant difference between the proportions of two independent groups?

  1. t-test

  2. ANOVA

  3. Chi-square test

  4. Regression analysis


Correct Option: C
