Q55 E - Chemistry (OpenStax)

Question

Consider the results of the archery contest shown in this figure. 

(a) Which archer is most precise? 

(b) Which archer is most accurate? 

(c) Who is both least precise and least accurate?

Step-by-Step Solution

Answer

(a) Archer X

(b) Archer W

(c) Archer Y

Step1: Definition of Accuracy:

The proximity of a result to the true value is defined as accuracy. This can be applied to a single measurement, but it is more usually used to calculate the mean of numerous repeated measurements, or replicates. Precision is defined as the degree to which outcomes agree with each other.

Step 2: Definition of Precise:

Precise is defined as "precise, as in interpretation, implementation, or amount." In physics, it means "periodic, dependable, and creating the same measurement every time."

Step 3: Archer Y being the least precise and accurate:

The reason is that his targets are all over the place with not one intended target.

Step 4: Archer X being the least accurate and high precise:

The reason is that it missed the entire target with intended target.

Step 5: Archer W being the most accurate:

The reason is that it hits the entire target area.
