  I give a short introduction to data ethics. I begin with some background
information and societal context for data ethics. I then discuss data ethics in
mathematical-science education and indicate some available course material. I
briefly highlight a few efforts -- at my home institution and elsewhere -- on
data ethics, society, and social good. I then discuss open data in research,
research replicability and some other ethical issues in research, and the
tension between privacy and open data and code, and a few controversial studies
and reactions to studies. I then discuss ethical principles, institutional
review boards, and a few other considerations in the scientific use of human
data. I then briefly survey a variety of research and lay articles that are
relevant to data ethics and data privacy. I conclude with a brief summary and
some closing remarks.
  My focal audience is mathematicians, but I hope that this chapter will also
be useful to others. I am not an expert about data ethics, and this chapter
provides only a starting point on this wide-ranging topic. I encourage you to
examine the resources that I discuss and to reflect carefully on data ethics,
its role in mathematics education, and the societal implications of data and
data analysis. As data and technology continue to evolve, I hope that such
careful reflection will continue throughout your life.
