What is fractional error or percent error?
A series of four measurements of the ratio of the circumference to diameter of a disk are made. The results of these measurements are: 3.140, 3.133, 3.132, 3.133. The average of the four measurements is the experimental value for Pi-Lab and the accepted value is Pi = 3.141. What is the percent error of these measurements?
a) 1 %
b) 2%
c) 0.5%
d)0.2%
A quadrilateral shaped area given by the following measurements have these corresponding probable errors: a = ±0.03m, b = ±0.05m, c = ±0.04m. and d = ±0.06m, what is the most probable error of the PERMIMETER to the nearest hundredths?
