Any number when expressed in the form of percentage conveys lot of meaning. Percentage is nothing but a number being expressed as a part of 100. This can be ratio of 100 or also can be termed as fraction. Percentage can be denoted by the symbol % and is very commonly used. Many measurements are made in the real world. So, there can be errors also. When there is deviation from the desired measurement error is obtained. It has to be measured to ascertain its cause and also to seek its remedy. At first the absolute is calculated. This is done by subtracting the value of the measurement obtained and the standard value. This will always be a positive number as absolute value of a number will always be positive. Once the absolute value is obtained the next step is to find the relative error which can be found if the value of the standard measurement is known. The relative error formula is quite simple. It is obtained by dividing the absolute error by the true value. If it has to be found in percentage then the answer obtained is multiplied by 100. So, the relative error equation is absolute error being divided by original value and multiplied by 100. The final answer is obtained in percentage.
This error is very significant and can be very helpful. It can be very useful in making a comparison between two measurements. The symbol percent is very important. One must not forget to write this after the answer is obtained as the answer obtained is in percentage. Also while rounding off the digits it has to be seen that the numbers do not lose their values. The terms relative error and absolute error are inter-related.
Understanding coordinate transformation is always challenging for me but thanks to all math help websites to help me out.
To calculate the former one first the latter one has to be calculated. So, the calculation of absolute error is very important and no mistake must be done while finding it out. To calculate the absolute value the standard value is required. This has to be available and if it is not then the term absolute error cannot be found out and the process cannot be completed. Error occurs in the real world as the instruments used cannot give 100% accuracy. So, the errors cannot be eliminated but they can only be reduced. When an error occurs it means there is deviation from true value.
