Final answer:
To analyze the data about weight perception, participants compare step weights to base weights. The step weight perceived as equivalent to a one-pound base weight indicates their threshold for weight change. The 20-pound group's perceptions of equivalent step weights may differ from those less accustomed to heavier weights.
Step-by-step explanation:
To analyze the data and report the results regarding weigh-ins, we must consider the specific details provided in the study or investigation being conducted. Generally, during a study that seeks to understand perceptions of weight increments, participants may be asked to compare various step weights to a base weight to assess their ability to detect differences in weight. For example, if all participants find a certain step weight to be equal to a one-pound base weight, this would indicate their threshold for detecting a weight change.
In the case of a specialized group, such as those accustomed to handling heavier weights, like the 20-pound group, their perception may differ. These individuals might interpret the feeling of weight increments differently due to their regular interaction with heavier objects. Therefore, the step weight that the 20-pound group finds to be equal may be higher or lower than that of less experienced individuals.
