This is a great place to start. When using ground beef to make hamburger patties, be sure to select the right meat. Lean ground beef like ground sirloin or the 7% fat meat will tend to make dry burgers.
Changes in lifestyles, nutrition, and ethnic composition of populations lead to changes in the distribution of body dimensions (e.g. the obesity epidemic), and require regular updating of anthropometric data collections.
When the second moment for a triangular distribution is calculated, it is found to have the value a 2 /24, where a is the overall width of the distribution. The square root of this quantity is taken to find the standard uncertainty which results in the value a /â24 or equivalently a /2 â6.
