Which image demonstrates poor accuracy but good precision

B

Explanation:

Accuracy is the proximity of a result to its real reference value. Thus, the greater the accuracy, the closer to the reference or real value the result is found.

Precision, on the other hand, is the degree of variation resulting from a set of measurements taken. Thus, the more precise a process is, the less the variability between the values found.

In the case of the figures shown above, figure B shows an example of a system that has low accuracy (because the balls are far from the hole) and good precision (because the balls are concentrated in the same location).

a. 35°c

b. 25°c

c. 10°c

d. 40°c
