What type of research is the only type of research that allows someone to determine a causal relationship between variables?
Controlled experiments establish causality, whereas correlational studies only show associations between variables. In an experimental design, you manipulate an independent variable and measure its effect on a dependent variable.
Which research method is used to study the relationships between variables?
A correlational study is a type of research design that looks at the relationships between two or more variables. Correlational studies are non-experimental, which means that the experimenter does not manipulate or control any of the variables.
Which type of research examines cause and effect between variables?
Experimental research, often called true experimentation, uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study.
Which type of research examines behavior in a natural setting without involvement of the experimenter?
Naturalistic observation is different than structured observation because it involves looking at a subject's behavior as it occurs in a natural setting, with no attempts at intervention on the part of the researcher.
