In this example, Clara conducted a trial run with a <u>small number of participants</u> to see if the instructions are clear and the experimental setting is plausible. Clara did this <u>before the actual study</u> and she did this trial run in a smaller scale, <u>her goal was to determine if the experimental setting was plausible and areas of improvement</u> (like the instructions), thus, this meets the requirements of a pilot study.
