Answer
A
It is a mathematical way of showing accuracy.
B
The higher the percent error, the more accurate the data set.
C
The higher the percent error, the less accurate the data set.
D
Only the experimental value is needed to calculate percent error.
E
Only the actual, or accepted, value is needed to calculate percent error.
F
A percent error always has a positive value.
Explanation
Percent error compares the experimental value with the accepted value, so it is a mathematical measure of accuracy. A larger percent error means the experimental result is farther from the accepted value and therefore less accurate. The formula uses the absolute difference between those values, so percent error is not negative.
