Experiment Description

A student researcher conducted a laboratory experiment to investigate the effect of auditory distraction on reading comprehension. She recruited an opportunity sample of 15 students who were studying in the university library.

  • Condition A: Participants read a short text passage while listening to upbeat instrumental music.
  • Condition B: Participants read an equivalent text passage in complete silence.

Reading comprehension was then measured using a 10-item multiple-choice questionnaire.

The researcher used opportunity sampling to select the participants for this experiment.
