Hello,

So for a problem there are 5 groups of 5 students each, and each group was given a metal rod of approximately 10 cm long to measure. Then all the measurements of each student are provided (each row is a group):

10.1 10.4 9.6 9.9 10.8

10.335 10.527 10.201 10.011 10.155

12.14 12.17 12.15 12.14 12.18

10.05 10.82 8.01 11.5 10.78

10 11 10 10 10

We are then asked which group had the most accurate measurements and which group had the most precise measurements. So for precision I know to calculate standard deviation and choose the group with the smallest but for accuracy I am confused on whether sig figs matter, or if accuracy is evaluated on how close each individual measurement is to 10 or how close the average is to 10. Would appreciate any help.
