In statistics, the coefficient of determination R2 is the proportion of variability in a data set that is accounted for by a statistical model. In this definition, the term variability is defined as the sum of squares. There are equivalent expressions for R2 based on an analysis of variance decomposition.
On average, an ostrich egg weighs about 1.4 Kg (3.1 pounds). On average, an ostrich egg weighs about 1.4 Kg (3.1 pounds).
Ostrich eggs contain less protein than chicken eggs -- 5 grams, compared to 6 grams -- but they're still a good source. Eating 1/4 cup of ostrich egg would supply a man with nearly 9 percent of his daily protein requirement and a woman with almost 11 percent of hers.
