 Steven Mudrinich, PMP Offline Expert Boarder Posts: 126 Karma: 6 Thank you received: 24 Anuj, It should be pretty intuitive on which formula to use on the exam, but here's a few ways to distinguish. If given a chart, the Triangular Distribution will plot as a triangle while the Beta Distribution will plot more as a bell curve. You'll see Triangular Distribution used more holistically to capture the statistics of an entire project without a ton of historical data to fall back on, while Beta Distribution is better when there is already historical data to compare with. Thus, Triangular is less accurate and more of a "guesstimate". Basically, if the exam asks you about new projects without a lot of available data or project experience, you are probably looking at using the Triangular Distribution. - Steven Comprehensive PMP Study Guide: www.amazon.com/Setting-Your-Exam-Study-P...rds=steven+mudrinich Your e-mail address will never be displayed on the site.
