____Your answer is here____

1). $Absolute- Error$ => The absolute error of the sum or difference of a number of quantities is less than or equal to the sum of their absolute errors.

__________________________

2). $Mean-Absolute-Error$ => It is possible to express MAE as the sum of two components: Quantity Disagreement and Allocation Disagreement. Quantity Disagreement is the absolute value of the Mean Error.

__________________________

3). $Relative - error$ => this type of error isrelative to the size of the item being measured. RE is expressed as a percentage and has no units.

_________________________

4). $Percentage- Error$ => Show the error as a percent of the exact value, so divide by the exact value and make it a percentage:

Example continued: 65/325 = 0.2 = 20%
