一项研究旨在确定大学生对自己身高和体重的估计有多准确。469名学生（136名女生和333名男生）完成了一份简短的问卷调查，问卷内容包括身高和体重的自我估计、测量的频率和频率、年龄和性别。随后，测量了他们的身高和体重。349名受试者被告知他们将在稍后接受测量；其他人没有被告知他们会被测量。数据分析显示，估计的绝对误差较小（1.00-3.54%）；男性和女性都高估了身高，低估了体重；女性对体重的估计比男性更不准确，对身高的估计比男性更准确；知道一个人的估计会通过测量来检验，这就产生了稍微更准确的估计。简单的自我估计身高和体重是足够精确的，可以用来代替测量。
A study was conducted to determine how accurately college students can estimate their height and body weight. Four hundred and sixty-nine students (136 females and 333 males) completed a short questionnaire eliciting self-estimates of height and weight, frequency and recency of measuring them, age, and gender. Immediately afterwards, their height and weight were measured. Three hundred and forty-nine subjects were told that they would be measured later; the others were not told that they would be measured. Analysis of the data revealed relatively small absolute errors of estimation (1.00-3.54%); both males and females overestimated height and underestimated weight; females estimated weight less accurately and height more accurately than males; and knowing that one's estimation would be checked by measurement produced slightly more accurate estimations. Simple self-estimates of height and weight are accurate enough to be used in place of measurements.
