What is the primary goal of quantitative psychology?

  1. To understand the relationship between variables

  2. To make predictions about future events

  3. To develop new theories

  4. To solve real-world problems

Show answer
Correct Option: A
Explanation:

Quantitative psychology is the branch of psychology that uses mathematical and statistical methods to study the relationship between variables.

Which of the following is an example of a quantitative research method?

  1. Experiment

  2. Survey

  3. Case study

  4. Naturalistic observation

Show answer
Correct Option: A
Explanation:

An experiment is a quantitative research method in which the researcher manipulates one or more variables to observe the effect on another variable.

What is a correlation coefficient?

  1. A measure of the strength of the relationship between two variables

  2. A measure of the direction of the relationship between two variables

  3. A measure of the statistical significance of the relationship between two variables

  4. All of the above

Show answer
Correct Option: D
Explanation:

A correlation coefficient is a measure of the strength, direction, and statistical significance of the relationship between two variables.

What is a regression analysis?

  1. A statistical method for predicting the value of one variable based on the values of other variables

  2. A statistical method for testing the relationship between two variables

  3. A statistical method for identifying the variables that are most important in predicting a particular outcome

  4. All of the above

Show answer
Correct Option: D
Explanation:

Regression analysis is a statistical method that can be used to predict the value of one variable based on the values of other variables, test the relationship between two variables, and identify the variables that are most important in predicting a particular outcome.

What is a factor analysis?

  1. A statistical method for identifying the underlying factors that explain the variance in a set of variables

  2. A statistical method for reducing the number of variables in a dataset

  3. A statistical method for creating a new set of variables that are uncorrelated with each other

  4. All of the above

Show answer
Correct Option: D
Explanation:

Factor analysis is a statistical method that can be used to identify the underlying factors that explain the variance in a set of variables, reduce the number of variables in a dataset, and create a new set of variables that are uncorrelated with each other.

What is a discriminant analysis?

  1. A statistical method for classifying individuals into two or more groups based on their scores on a set of variables

  2. A statistical method for identifying the variables that are most important in discriminating between two or more groups

  3. A statistical method for creating a new set of variables that are maximally discriminant between two or more groups

  4. All of the above

Show answer
Correct Option: D
Explanation:

Discriminant analysis is a statistical method that can be used to classify individuals into two or more groups based on their scores on a set of variables, identify the variables that are most important in discriminating between two or more groups, and create a new set of variables that are maximally discriminant between two or more groups.

What is a cluster analysis?

  1. A statistical method for identifying groups of similar individuals within a dataset

  2. A statistical method for reducing the number of variables in a dataset

  3. A statistical method for creating a new set of variables that are uncorrelated with each other

  4. All of the above

Show answer
Correct Option: A
Explanation:

Cluster analysis is a statistical method that can be used to identify groups of similar individuals within a dataset.

What is a multidimensional scaling analysis?

  1. A statistical method for representing the relationships between a set of variables in a two-dimensional space

  2. A statistical method for reducing the number of variables in a dataset

  3. A statistical method for creating a new set of variables that are uncorrelated with each other

  4. All of the above

Show answer
Correct Option: A
Explanation:

Multidimensional scaling analysis is a statistical method that can be used to represent the relationships between a set of variables in a two-dimensional space.

What is a structural equation modeling?

  1. A statistical method for testing the relationships between a set of variables

  2. A statistical method for identifying the variables that are most important in predicting a particular outcome

  3. A statistical method for creating a new set of variables that are uncorrelated with each other

  4. All of the above

Show answer
Correct Option: A
Explanation:

Structural equation modeling is a statistical method that can be used to test the relationships between a set of variables.

What is a time series analysis?

  1. A statistical method for analyzing data that is collected over time

  2. A statistical method for identifying the trends and patterns in a time series

  3. A statistical method for forecasting future values of a time series

  4. All of the above

Show answer
Correct Option: D
Explanation:

Time series analysis is a statistical method that can be used to analyze data that is collected over time, identify the trends and patterns in a time series, and forecast future values of a time series.

What is a meta-analysis?

  1. A statistical method for combining the results of multiple studies

  2. A statistical method for identifying the variables that are most important in predicting a particular outcome

  3. A statistical method for creating a new set of variables that are uncorrelated with each other

  4. All of the above

Show answer
Correct Option: A
Explanation:

Meta-analysis is a statistical method that can be used to combine the results of multiple studies.

What is a quantitative psychology?

  1. The branch of psychology that uses mathematical and statistical methods to study the relationship between variables

  2. The branch of psychology that studies the mind and behavior of humans and animals

  3. The branch of psychology that studies the development of children and adolescents

  4. The branch of psychology that studies the relationship between culture and behavior

Show answer
Correct Option: A
Explanation:

Quantitative psychology is the branch of psychology that uses mathematical and statistical methods to study the relationship between variables.
