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 looking at results, the P value is important. P stands for probability. It measures the likelihood that a particular finding or observed difference is due to chance. The P value is between 0 and 1. The closer the result is to 0, the less likely it is that the observed difference is due to chance.
