Research Methods Quiz

What is the main focus of correlational research?

• Manipulating variables

• Examining the relationship of two variables

• Creating cause and effect relationships

• Controlling the environment

Which type of correlation involves an increase in one variable corresponding to an increase in another variable?

• Negative correlation

• Non-correlation

• Zero correlation

• Positive correlation

What is the purpose of a control condition in experimental research?

• To manipulate variables

• To observe and measure variables

• To ensure treatment has an effect

• To compare treatment and non-treatment conditions

In nonexperimental research, what is the quasi-independent variable used for?

• Observing and measuring variables

• Controlling the environment

• Creating different group scores

• Manipulating variables

What type of research design examines the relationship between variables without true experiments?

• Quasi-experimental research

• Correlational research

• Nonexperimental research

• Experimental research

Which method of data collection is used in correlational research to prove a statistical relationship between variables?

• Experimental observation

• Archival data method

• Controlled experiment

• Field study

What is the main characteristic of a negative correlation?

• One variable increases while the other decreases

• No statistical connection between variables

• Both variables decrease together

• Both variables increase together

What is the purpose of manipulating variables in experimental research?

• To observe and measure variables

• To create a cause and effect relationship

• To compare group scores

• To ensure control over the environment

Which type of research involves a natural relationship between variables and does not manipulate variables using the scientific method?

• Nonexperimental research

• Correlational research

• Experimental research

• Quasi-experimental research

What is the role of the independent variable in experimental research?

• To compare group scores

• To manipulate the variables

• To ensure control over the environment

• To observe and measure the effect of the treatment
