• The idea that "people's emotions and personal beliefs often override their acceptance of objective facts" is

expressed in the dictionary definition of

• false news. 2 / 4

• post-truth.
• powerful examples.
• repetition.
• Professor Terrance has conducted a study that examined the relationship between level of physical

activity and academic performance among children. He is most likely to use to determine if a relationship exists.

• meta-analysis
• preregistration
• a correlation coefficient
• experimental research

• The tendency to perceive order in random events often leads to overestimating the value of
• common sense.
• operational definitions.
• informed consent.
• the double-blind procedure.

• Dr. Carlson wants to conduct a research study that will examine the sexual behaviors of college students.

Before she can begin data collection she must submit her research proposal to

• Unconscious gut feelings, or , provide(s) a sharp contrast to explicit, conscious reasoning.
• theory
• chance-based explanation
• common sense

• The explanatory power of a scientific theory is most closely linked to its capacity to generate testable
• assumptions.
• correlations.
• predictions.
• variables.

• Several weeks after a political election, voters often exaggerate their ability to have predicted the election

• When we ask, for example, how closely related are the intelligence scores of fraternal twins, we are asking

how strongly two are related.

• experimental groups
• control groups
• variables
• scatterplots

• When you read a bar graph, it is most important for you to
• mentally transform the data into a normal curve.
