Textbook Question

Chapter 2.2, Problem 29E

Participants in a study of honesty in online dating profiles were recruited through print and online advertisements in the Village Voice, one of New York City’s most prominent weekly newspapers, and on Craigslist New York City (“The Truth About Lying in Online Dating Profiles,” Computer-Human Interaction [2007]: 1–4). The actual height, weight, and age of the participants were compared to what appeared in their online dating profiles. The resulting data was then used to draw conclusions about how common deception was in online dating profiles.

What concerns do you have about generalizing conclusions based on data from this study to the population of all people who have an online dating profile? Be sure to address at least two concerns and give the reasons for your concern.
