A percentage of correct answers on some test, or the number of seconds needed to complete a particular task, can be assessed directly, and therefore are both good examples of __________.

A) dependent variables
B) independent variables
C) demand characteristics
D) confounds

Dependent variables are the variables that are being measured in an experiment or study, which can be assessed directly such as percentage of correct answers on a test or the time taken to complete a task. Independent variables are the variables that are being manipulated or controlled by the researcher, demand characteristics refer to cues or signals that can influence participants' behavior, and confounds are variables that can impact the results of the study but are not being intentionally manipulated by the researcher.
