Quick comprehension check
“A student measures the mass of an object known to be 50.0 grams. Their measurements are 48.5 g, 49.2 g, and 51.1 g. Calculate the percent error of the 48.5 g measurement. Show your work. A student measures the length of a table three times and obtains the following measurements: 1.51 m, 1.49 m, and 1.50 m. Calculate the range of these measurements. Show your work. A chemist performs an experiment and gets the following three results: 10.2°C, 10.1°C, and 10.3°C. The actual value is known to be 10.1°C. Are the chemist's measurements accurate, precise, both, or neither? Explain your answer.”
