The study examined 40 students’ explanations of a statement referring to decreases in variance with sample size. Content analysis coded 22 explanation features. Four groups of subjects were defined. Five undergraduates were unsure of the relationship described in the statement. A second group reversed the statement; a diversity-based view of within sample variability was proposed to explain the...

This work focuses on the size distribution of sneeze droplets exhaled immediately at mouth. Twenty healthy subjects participated in the experiment and 44 sneezes were measured by using a laser particle size analyser. Two types of distributions are observed: unimodal and bimodal. For each sneeze, the droplets exhaled at different time in the sneeze duration have the same distribution characteris...
