Dr. Larson was interested in whether classical music helps students perform better on a test. Dr. Larson randomly assigned half of the study's participants to a group that listened to classical music while taking a test. The other half of the participants did not listen to music while taking a test. The research design Dr. Larson used is...
a case study
an experiment
an observation
a survey
Researchers were interested to know whether internal vehicle temperatures vary by outside temperatures. To evaluate this, temperature rise was measured continuously over a 60-minute period in a dark SUV on 16 different clear, sunny days with outside temperatures ranging from 72oF to 96oF. The researchers' method of analysis is best described as:
a census.
a survey.
an observational study.
an experiment.
To test the effects of breakfast on grades I ask my students if they ate breakfast and then compare the breakfast eaters grades to the non-breakfast eaters.
This is an example of:
