Histograms and the PMP Certification

By: Megan Bell, MPM, PMP April 21st, 2021

Project Managers know how clients will react when presented with large amounts of data in the form of a spreadsheets with hundreds (better yet, thousands!) of rows of numbers with no context or clear meaning; it will not be a reaction of gratitude. On the other hand, if that same large dataset is presented using data visualization and a quality tool, like a histogram, then the client will be able to see the connection to the project decision needed. Histograms are a statistical tool included in the Project Management Professional (PMP)® certification exam as they are used by project managers to plan and manage quality.
