Question 2 Multiple Choice (Single Answer)

What is the purpose of hypothesis testing in quantitative psychology?

  1. To confirm a hypothesis
  2. To reject a hypothesis
  3. To determine the probability of a hypothesis being true
  4. To generate new hypotheses
Question 3 Multiple Choice (Single Answer)

What is the difference between a descriptive statistic and an inferential statistic?

  1. Descriptive statistics summarize data, while inferential statistics make predictions about a population.
  2. Descriptive statistics are used to describe a sample, while inferential statistics are used to generalize to a population.
  3. Descriptive statistics are based on observed data, while inferential statistics are based on theoretical models.
  4. All of the above

  1. t-test
  2. ANOVA
  3. Regression analysis
  4. All of the above
Question 6 Multiple Choice (Single Answer)

What is the purpose of experimental design in quantitative psychology?

  1. To control for confounding variables
  2. To ensure that the results of a study are valid and reliable
  3. To increase the likelihood of finding a statistically significant result
  4. All of the above
Question 7 Multiple Choice (Single Answer)

What is a confounding variable?

  1. A variable that is related to both the independent and dependent variables
  2. A variable that is not related to either the independent or dependent variables
  3. A variable that is related to the independent variable but not the dependent variable
  4. A variable that is related to the dependent variable but not the independent variable
Question 8 Multiple Choice (Single Answer)

What is the difference between a correlation and a causation?

  1. A correlation is a relationship between two variables, while a causation is a relationship in which one variable causes the other.
  2. A correlation is a relationship between two variables that are both affected by a third variable, while a causation is a relationship in which one variable directly causes the other.
  3. A correlation is a relationship between two variables that are both random, while a causation is a relationship in which one variable is determined by the other.
  4. A correlation is a relationship between two variables that are both measured at the same time, while a causation is a relationship in which one variable is measured before the other.
Question 9 Multiple Choice (Single Answer)

What is the purpose of regression analysis in quantitative psychology?

  1. To predict the value of a dependent variable based on the values of one or more independent variables
  2. To determine the relationship between two or more variables
  3. To control for confounding variables
  4. All of the above
Question 10 Multiple Choice (Single Answer)

What is the difference between a simple regression and a multiple regression?

  1. A simple regression has one independent variable, while a multiple regression has two or more independent variables.
  2. A simple regression is used to predict the value of a continuous dependent variable, while a multiple regression is used to predict the value of a categorical dependent variable.
  3. A simple regression is used to determine the relationship between two variables, while a multiple regression is used to control for confounding variables.
  4. A simple regression is used to make predictions about a population, while a multiple regression is used to make predictions about a sample.
Question 11 Multiple Choice (Single Answer)

What is the purpose of factor analysis in quantitative psychology?

  1. To reduce the number of variables in a dataset
  2. To identify the underlying structure of a dataset
  3. To create a new set of variables that are uncorrelated with each other
  4. All of the above
Question 12 Multiple Choice (Single Answer)

What is the difference between exploratory factor analysis and confirmatory factor analysis?

  1. Exploratory factor analysis is used to generate hypotheses about the structure of a dataset, while confirmatory factor analysis is used to test hypotheses about the structure of a dataset.
  2. Exploratory factor analysis is used to identify the underlying factors in a dataset, while confirmatory factor analysis is used to determine the number of factors in a dataset.
  3. Exploratory factor analysis is used to create a new set of variables that are uncorrelated with each other, while confirmatory factor analysis is used to reduce the number of variables in a dataset.
  4. Exploratory factor analysis is used to make predictions about a population, while confirmatory factor analysis is used to make predictions about a sample.
