Question

Do I need to know where on the dart board the 3, 1, 5 cm darts landed to obtain precision and accuracy?

For the data and calculation for this lab report assume that a dart was thrown at bullseye 3 times with the aim of hitting the middle, the 3 distance from the middle obtain where 3cm, 1cm, and 5cm. Calculate the average, the percent error and discuss in your lab report and emphasize on the accuracy vs precision part

Answer 1

This case is regarding accuracy and precision. percent error can not be found because the percent error calculates the error or percentage deviation from the expected value.

percentage error = (what is derived - what you were supposed to derive) / what you were supposed to derive * 100

here in this case, what is derived and what was supposed to be derived can not be actually measured.

the deviations are the distance of the darts from each other

however in dart and board, either you hit the bulls eye, that is 0 error or u don't hit the bullseye, that is 100% error

there is nothing in between

the hit of the dart can be evaluated on the precision and accuracy part.

accuracy is how close the darts are to the bullseye. if we see from the distance point of view darts are at an average distance of 3 cm (3+1+5)/3=3

precision is how close the darts are to each other and not to the bullseye. the distance between the 3 darts will evaluate the precision point.
