Question

Spongebob was trying to make Krabby Patties that weighed 12oz. He made 4 Krabby Patties. They all had the following weights: 12.12oz; 11.9oz; 12.2oz; 12.1oz. Is this an example of Accuracy? Precision? Both? Neither?

Answer 1

Step-by-step explanation:

Step 1: Determine what precision and accuracy is

According to online, "precision is how close measure values are to each other, basically how many decimal places are at the end of a given measurement. Precision does matter. Accuracy is how close a measure value is to the true value. Accuracy matters too, but it's best when measurements are both precise and accurate."

Step 2: Determine which are displayed in this problem

We can see that most of these weight are really close to the original weight which means that the accuracy is pretty high. This means that our weights are fairly close to the original predicated amount.

We can also see that our precision is somewhat decent because most of the numbers bunch up around each other. Precision and accuracy don't have to occur at the same time. For example, a precise collection can be 15, 15.01, 14.99. Although they are far away from the original point, they are bunched up together giving a high precision.

Answer 2

Yes, the 4 Krabby patties are an example of high precision.

Explanation:

Precision is the closeness of the values ​​obtained by applying them to the same parameter. To calculate the precision, the closeness of each of the values ​​with the mean must be determined, all the values ​​will be taken by subtracting the mean and the values ​​will be taken into account to know which are the most accurate.

(12.12 + 11.9 + 12.2 + 12. 1) / 4 = 12.08

12.12 - 12.8 = 0.04

11.9 - 12.08 = - 0. 18

12.2 - 12.08 = 0.12

12.1 - 12.08 = 0.02

The most accurate precision is that of the fourth Krabby Pattie and the least precise is that of the second.
