Question

a student reports three trials to measure the density of an unknown metal. the percent error in these trials is given in the table.

trial count	percent error
trial 2	0.02
trial 3	0.01

indicate the trial that has the most accurate value and explain why.

Explanation:

Percent error measures the deviation between a measured value and the true value, with a smaller percent error indicating greater accuracy. Comparing the percent errors: Trial 1 has 0.05, Trial 2 has 0.02, and Trial 3 has 0.01. Since 0.01 is the smallest among these values, Trial 3 has the least deviation from the true density value of the metal, so it is the most accurate.

Answer:

Trial 3
