Each student measured the volume and mass of three separate samples. They reported calculated densities for each trial and an average of the three calculations. The powder, sucrose (table sugar), has a density of 1.59 g/cm². Q1. Which student collected the most accurate data? Q2. Who collected the most precise data? Using the table above as reference, analyze and provide answers to the given questions. The density values reported in the table above are experimental values, which means they are measured during an experiment. The known density of sucrose is an accepted value, which is a value considered true. To evaluate the accuracy of experimental data, you can compare how close the experimental value is to the accepted value. Error is defined as the difference between an experimental value and an accepted value. Compute for the value of errors in the table given.

Consider the data in the table. Students were asked to find the density of an unknown white
powder. Each student measured the volume and mass of three separate samples. They reported
calculated densities for each trial and an average of the three calculations. The powder, sucrose
(table sugar), has a density of 1.59 g/cm².
Q1. Which student collected the most accurate data? Q2.Who collected the most precise data?
Using the table above as reference, analyze and provide answers to the given questions.
The density values reported in the table above are experimental values, which means they
are measured during an experiment. The known density of sucrose is an accepted value, which is a
value considered true. To evaluate the accuracy of experimental data, you can compare how close
the experimental value is to the accepted value. Error is defined as the difference between an
experimental value and an accepted value. Compute for the value of errors in the table given.
