About the Course
Introduction
This CLE course will guide trial lawyers on the use of statistical analyses in class litigation.
Description
Increasingly, statistical evidence is used by both sides to argue the makeup of the class, damages, liability, and certification in every type of case: employment, data breach, ESG, antitrust, consumer product, and commercial class action cases. Economists and practitioners can use statistics to measure the impact on individual members and show where there is no impact.
Class action lawyers must be able to analyze both the methodology and inferential process that produce statistical evidence, and their effect on admissibility, relevance, and strength of the resulting evidence.
Listen as our experienced panel of practitioners examines the use of statistics in class litigation and the implications of recent case law for class litigators seeking to use or restrict these kinds of evidence during class certification and trial.
