Fraction error analysis
Did you know?
WebThe relative error (also called the fractional error) is obtained by dividing the absolute error in the quantity by the quantity itself. The relative error is usually more significant than the absolute error. For example a 1 mm error in the diameter of a skate wheel is probably more serious than a 1 mm error in a truck tire. WebThe analysis is based on a twenty-five question test covering five categories: (1) Algorithmic applications; (2) Applications of basic fraction concepts in word problems; (3) Elementary algebraic concepts; (4) Specific arithmetic skills that are a prerequisite to algebra; and (5) Comprehension of the structure of rational numbers.
