The accepted value for the density of iron is 7.9 g/mL. Four student groups examine the density of iron in the lab. Which of the
nalin [4]

For 5.43 g/mL and 5.44 g/mL =  0.01 the least diff and most precise.

First of all, precision is determined by the difference in the two obtained values. If the difference between the two values obtained is less, then precision is more. If the difference between the two values obtained is more, then precision is less.

For 5.43 g/mL and 5.44 g/mL , we can see that the difference between these two data is 0.01

For 7.98 g/mL and 7.91 g/mL , we can see that the difference between these two data is 0.07

For 7.65 g/mL and 7.64 g/mL , we can see that the difference between these two data is 0.01

For 7.06 g/mL and 7.03 g/mL , we can see that the difference between these two data is 0.03

As we can see that, the most difference between the data is 0.07 between 7.65 g/mL and 7.64 g/mL and thus, they are least precise.
