Attempts: Keep the Highest: /5 1. Identifying related samples Aa Aa For each of the following research scenarios, decide whether the sign uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers ca subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples.) n match A researcher is interested in whether people eat more or less when they are in a hurry. The researcher collects a random sample of 80 adults and invites them to eat two (identical) free meals one month apart. For one of the meals, no time restriction is placed on the meal.

B) The subjets from the both samples are not the same subjects, moreover they aer not similar. Thus, for this example, answer is "does not use related sample"
