Fundamentals of Scientific Inquiry in Psychology Quiz

A hypothesis is a tentative explanation based on observation and reasoning.

Naturalistic observation involves observing and recording behavior in naturally occurring situations without manipulating variables.

After forming a hypothesis, the next step in the scientific method is designing the experiment.

In an experimental study, the independent variable is deliberately manipulated by the researcher.

The purpose of a control group is to provide a comparison for the experimental group.

A confounding variable is a variable that changes along with the independent variable and may affect the dependent variable.

The primary purpose of peer review is to assess the quality and validity of research before publication.

Subjectivity is not a characteristic of a good scientific theory.

The purpose of replication is to ensure that research findings are consistent and reliable.

Operational definitions in psychological research provide a clear and measurable definition of variables.

The correlation coefficient indicates the strength and direction of a relationship between two variables.

The purpose of random assignment is to increase the likelihood that experimental and control groups are equivalent at the start of the experiment.

In a double-blind experiment, both the participants and the researchers are unaware of which participants are in the experimental and control groups.
