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 1 | 0.05
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 (accepted) value. A smaller percent error means the measured value is closer to the true value, 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's measured density is closest to the actual density of the metal, so it is the most accurate.

Answer:

Trial 3 has the most accurate value.
