Abstract
A main difficulty in the study of statistical inference is the understanding of the concept of sampling distribution. In this work, we summarize the main difficulties described in the research on the subject and analyze its comprehension by secondary and high school students. For this purpose, the mean and range of four values provided by students of three different courses to a task related to the binomial distribution are studied. The results show a reasonable understanding of the expected value, although some students show the equiprobability bias. The understanding of sampling variability is poor, but improves with age.
