question 37

Multiple Choice

Resonance: When an LRC series circuit is driven at resonance, which of the following statements about the circuit are correct? (There may be more than one correct choice.)

• A) The impedance of the circuit is zero.
• B) The impedance of the circuit has its maximum value.

Definitions:

Confounds

Variables that are not controlled in a research study, potentially leading to incorrect conclusions by mixing their effects with those of the variables of interest.

Confounds

Variables that confuse the outcome of an experiment by influencing the dependent variable in addition to or instead of the independent variable.

Manipulation Checks

Assessments used in experimental research to determine if the independent variable has been successfully manipulated.

Statistically Significant

Indicates that the likelihood of the observed result occurring by chance is low, suggesting a true effect in a study.
