VARIABLE INTERVAL SCHEDULE OF REINFORCEMENTProbably, the situation implies the answer stated above which is the "Variable Interval Schedule of Reinforcement". In operant conditioning, a
variable-interval schedule is a schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed. This schedule produces a slow, steady rate of response.

<u>Question 1</u>
The correct answer is: "The researchers administered a questionnaire to obtain their data without trying to influence an explanatory variable of the study".
An observational study is one in which the researcher observes the effect of a variable without manipulating the conditions that surround the exposure or the subjects who are exposed to it. In this example, he simply hands out questionaires to the 353 individuals that compose the sample drawn from the population of interest: 12-year old teenagers.
