It affects the precision of the measurements.

Question

A. random errors

B. systematic errors

C. variance

D. percent error

Answer 1

The answer is A.

Random errors lead to imprecision. Systematic errors are errors that are reproducible and lead to errors in accuracy.

Variance is a mathematical formula that serves as a measure of imprecision.

Percent error is a calculation that measures accuracy ( Value obtained - True Value) / True Value x 100
