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.
Although a statistical test might commonly use an approximation, it does not mean it cannot be calculated using the true probability distribution. For example, an asymptotic p-value for the Pearson X2 test uses the chi-squared approximation, but the test could also compute an exact p-value using the true probability distribution.
