How To Determine Number And Size Of Histogram Bins
"I have several thousand rows of data which I need to group into appropriate sized bins for a histogram. The problem is in determining the correct number and size for each bin, i.e. if I had a bunch of test scores and didn't have pre-determined bins (A,B,C,D,F) that were already sized (> 90, 80-89, 70-79, 60-69, <60), how would I figure out the number and size of the bins?" From the iSixSigma Discussion Forum.

About iSixSigma Military

The purpose of this iSixSigma Military channel is to document the transformation of the United States Armed Services through the use of Lean Six Sigma and related process improvement methodologies.

Ronald E. Rezek, special assistant to the acting secretary of the Army, has said the goal of the Army's Lean Six Sigma deployment is to "make the business side of the Army as efficient as the war-fighting side is effective." Leaders of the other armed services echo that sentiment and transformation objective.

This portal will serve as a central community for everyone associated with the business transformation of the U.S. military. It will provide communication updates on deployments, the opportunity for military leaders at all levels to learn new skills, advance their careers and contribute to the success of their organizations.
