relative error and magnitude

The difference between these two values is called the absolute error. Absolute Error = Original number - Approximated number The ratio of the absolute error and the original number expressed in percentage form is called percentage relative error..

From the above examples on approximation, we observe that the approximated value may be more or less than the original number. The difference between these two values is called the absolute error. Absolute Error = Original number - Approximated number The ratio of the absolute h..

The ratio of the maximum error to time value of the measured quantity. Where arithmetic mean is taken as time value..

These are irregularly occurring errors, which are at random, in magnitude and direction. They are not due to any definite cause and hence, are called accidental errors. A person may get different readings while experimenting, say, for E.g., while measuring the diamete..

Find the ratio of relative error in the area A of a circle to the relative error in the circumference S of the circle. => 3 : 1 or 1 : 2 or 2 : 1 or 2 : 3 or 1 : 1..

If an error of 0.05 cm is made while measuring the side 2 cm of an equilateral triangle, then find the relative error in its area. => 20 or 0.1 or 0.05 or 0.0025 or 0.2..

In a similar way, the relative velocity V A with respect to V B , that is, V A B can also be determined. The figure below illustrates this case. It can be seen that the magnitude of relative velocity in both cases is the same with the direction reverse..

Which of the following statement(s) is/are false? I. Data such as blood types (A, B, AB, O) can be organised into a categorical frequency distribution. II. Except for rounding errors, relative frequencies should add up to 100. III. A statistical device used in exploratory data a..

We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. The difference between these two values is called the absolute error. Absolute Error = Original number - Ap..

The SI units of some of the physical quantities are either too small or too large. To change the order of magnitude, the metric system, which is a decimal system, relates this in powers of ten. These powers are indicated by prefixe..
