Abstract
In order to assess precisely the impact of workers' aptitude on productivity, we have made a series of experimental studies and questionnaires. However, because the workers were university students in all of these experiments and questionnaires, it is necessary to clarify whether the results of experiment questionnaire obtained from the student workers can also be fitted to general workers. In this paper, we hire 40 workers from the general public and conduct cell production experiment. Then, we make several statistical comparisons between student workers and general workers. It was clarified that the assembly times of student workers are generally shorter than the general workers.
