Questions: A researcher asks an assistant to conduct a study on her behalf. She specifically tells her assistant only to share the results anonymously and not to include the names of the students along with their scores. Such an experiment would be considered a single-blind experiment, laboratory observation, double-blind experiment, correlational study.

The answer is single-blind experiment.

In a single-blind experiment, the participants do not know certain details about the experiment, such as whether they are in the control or experimental group. In this context, the anonymity of the students' scores suggests that the participants (students) are not aware of how their individual data is being used, aligning with the concept of a single-blind experiment.

Laboratory observation involves observing subjects in a controlled environment, typically without manipulating variables. This option does not fit the description of the study, as the focus is on anonymity rather than observation.

In a double-blind experiment, neither the participants nor the experimenters know who is receiving a particular treatment. The scenario described does not mention the experimenter being unaware of the conditions, so this option is not applicable.

A correlational study examines the relationship between two or more variables without manipulating them. While the study could be correlational, the emphasis on anonymity aligns more closely with the concept of a single-blind experiment.
