expalin me errors how to claculate |
|
Answer» For calculating errors first we have to find the average of the given digits or value...by An=A1+A2+A3+An/N .....this is the formula of average..Then, for absolute error we have to substract all the given digits or value by the average answer....just like : An-A1, An-A2....... by this we find all absolute error... Absolute error ,relative error and percantage error are important for exam Error =true value - measured value |
