Correlational Research Quiz

What is the primary purpose of correlational research?

• To establish cause and effect relationships

• To determine relationships between variables

• To manipulate variables in an experiment

• To observe phenomena without intervention

Which statistical method is most commonly used in correlational research?

• Analysis of Variance (ANOVA)

• Regression Analysis

• Pearson's r

• Chi-Square Test

What does a correlation coefficient of -1.00 represent?

• No relationship between variables

• A weak positive relationship

• A perfect negative relationship

• A strong positive relationship

Which type of correlational study is focused on using one variable to forecast another?

• Relationship study

• Prediction study

• Experimental study

• Descriptive study

What is a key difference between explanatory and prediction designs in correlational research?

• Prediction designs use simple statistical methods, while explanatory designs use advanced ones.

• Explanatory designs use advanced statistical methods, while prediction designs focus on future outcomes.

• Explanatory designs are qualitative, while prediction designs are quantitative.

• Explanatory designs study cause and effect, while prediction designs do not.

In correlational research, which variable is used to predict an outcome?
