Question

In a lab, Jose measured the weight of a penny multiple times and has the measurements of 3.50 g, 3.51 g, and 3.48 g. When Jose measures the same object multiple times and they are close together, what is he demonstrating?

A) Accuracy
B) Meniscus
C) Scientific Notation
D) Precision

Answer 1

Jose is demonstrating precision by consistently measuring the weight of a penny with little variation among the measurements.

Step-by-step explanation:

When Jose measures the weight of a penny multiple times with the measurements of 3.50 g, 3.51 g, and 3.48 g, and these measurements are close together, he is demonstrating precision. Precision in scientific measurements refers to how close the measurements are to each other, regardless of whether they are close to the true or accepted value (accuracy). The consistency of Jose's measurements indicates a high degree of precision because they vary by a very small amount.
