Chapter 07.03 Exercise Question 04

7.3.4

In a study of parents' perceptions of their children's size, researchers Kaufman et al. (Current Biology, 2013) asked parents to estimate their youngest child's height. The researchers hypothesized that parents tend to underestimate their youngest child's size because the youngest child is the baby of the family and everybody else is the family appears bigger compared to the baby. The sample of31

parents who were surveyed underestimated their youngest child's height by7.1

cm, on average; the standard deviation for the difference in actual heights and estimated heights was6.98

cm and the data are not strongly skewed.
