Easy Techniques to Prepare your Data for Analysis
Date: Monday July 12, 2021 at 1:00-2:00 EDT
Speakers: Alan Safer and Lesley Farmer
Data analysis can lead to more informed and effective decisions – but that analysis is only as good as the data gathered and organized. The saying “garbage in, garbage out” certainly applies to data sets. Therefore, it is imperative to “clean” or “scrub” your data set before conducting statistical tests on it. This session gives you tips for dealing with messy data: incomplete or missing data, extreme numbers, typos, miscoding, and inappropriate assumptions. You’ll find that taking the time to prep your data set is a good return on your investment of labor.
