Final Paper

Prepare an eight- to ten- page paper (excluding the APA reference and title pages) comparing and contrasting the Frye standard, [Frye vs. United States (293 F. 1013 (DC Cir 1923)], with the Daubert standard [Daubert v. Merrell Dow Pharmaceuticals (509 U.S. 579 (1993)], for the admissibility of scientific evidence. At a minimum, the paper must include the following:
A factual history for both cases
The issues for both cases
