Question

What statements best define percent error? Check all that apply.

It is a mathematical way of showing accuracy.The higher the percent error, the more accurate the data set.The higher the percent error, the less accurate the data set.Only the experimental value is needed to calculate percent error.Only the actual, or accepted, value is needed to calculate percent error. A percent error always has a positive value.

Answer 1

Answer: It is a mathematical way of showing accuracy.The higher the percent error, the less accurate the data set.

Explanation:

Percent error is the difference between the experimental value and theoretical value and measures the accuracy of the result found. The larger the error, lesser is the accuracy and vice versa.

`{\text {percent error}=\frac{|\text {Accepted value- Experimental value}|}{\text {accepted value}}`

The experimental value can be greater or smaller than accepted value thus percent error can be positive as well as negative. But we only consider the value without the sign.
