One way in which experimental research differs from observational research is that only experimental research can?

establish causality between variables by manipulating one variable and measuring its effect on another variable. Observational research can observe and describe associations between variables but cannot determine cause-and-effect relationships.

The three types of field work are observational, experimental, and survey research. Observational field work involves observing and documenting natural behavior. Experimental field work involves manipulating variables to test hypotheses. Survey research involves collecting data through direct interaction with participants.

What are the three research methods typically used by ecologists?

The three research methods typically used by ecologists are observational studies, experimental studies, and modeling. Observational studies involve gathering data from natural environments without manipulating variables. Experimental studies involve manipulating variables to test hypotheses. Modeling involves creating mathematical or computer models to simulate ecological processes.

How are observational studies of populations different from experimental studies?

Observational studies observe natural phenomena without intervention, while experimental studies manipulate variables to determine cause and effect. Observational studies are useful for understanding associations, while experimental studies can establish causal relationships between variables. Experimental studies involve random assignment of participants to groups, while observational studies rely on natural groupings.


What research designs collect data?

Experimental, correlational, observational, and qualitative research designs are common approaches that collect data. Each design has its own methodology and purpose for collecting data to address specific research questions or hypotheses.
