NEED EXPLANATION Suppose Ashley and Ryan each throw darts at targets as shown below. Each of themis trying very hard to hit the bulls eye each time. Which one is better? Explain interms of the average value and uncertainty of their hits.AshleyRyan

Two-person Ashley & Ryan are throwing darts at the targets shown above in question. Each of them is trying to hit the center each time. (A) Explanation on basis of Average Value: Precision is defined as the measurement in which one where independent measurements of the same quantity closely cluster about a single value that may or may not be the correct value. Accuracy measurement is one where independent measurements cluster about the true value of the measured quantity. For Ashley, we can clearly say he has low precision and low accuracy for which darts points are at distinct points for which the average value will not be closer to the center. For Ryan, we can clearly say he has high precision and low accuracy for which dart points are close together but the average value is not close to the center value. So, according to the average value, no one is better.(B)Explanation on basis of Uncertainty Value: Uncertainty is defined as the measurement that can be taken in plus-minus value with the center value or in plus-minus percentage value with the center value. For Ashley, we can clearly say he has a percentage value of uncertainty which has low precision and low accuracy for which the average value will not be closer to the center. For Ryan, we can clearly say he has an absolute value of uncertainty which has high precision and low accuracy for which the average value will not be closer to the center. So, according to the uncertainty value, no one is better.
