摘要：大数例の計測を行なう場合, その数値が3〜4桁以上になるときは, 末端位の数は理論的に0〜9まで平等に出現するはずである. 諸種の計測, 計量値すなわち人口数, 温度測定値, 身長, 体重, 血圧などを計測した結果, その値の末端位数の分布が, 理論的分布と一致しているか否かを, x^2-testによって確かめ, 計測の難易度, 精度及び被測定者の管理状態の良否について検討した. 人口動態統計のような計数値では, その末端位値では, 0〜9に平等に分布する. また, 計量数値では, 指示目盛を固定し得るものに比して, 動揺中に測定値を読みとらなければならない場合は, 末端位数はより多く0と5に偏って集まる. とくに体重の測定値では, 被測定者の年令が進むにつれて, 末端位数が0と5に集中する傾向が著しく, 測定に対する計測者および被測定者ゐ安易な態度がうかがわれる.
其他摘要：The appearance of the last digit of any number, composed of several digits, as a result of a measurement out of large number of samles, is expected to be evenly distributed between figures zero and nine. Variety of measurement results, such as population, reading in thermometer, height, weight and blood pressure, were collected in order to ascertain the hypothesis above by applying x^2-test. This, in turn, would mean an exmination of validity and reliability in administration of data. The hypothesis was proved to be correct in the cases of demographic values. Among the measurement recordings, the last digit appeared more frequently to be figures zero and five, when the value had to be momentarily recorded as the dial indicator was not well fixed, than the cases when it could be fixed. The body weight readings showed this trend most greatly as the age of subjects advanced. The results indicate the unstrict attitude of the tester and the subject towards accurate measurement under certain circumstances.
