#### Answer

a. Imprecise and inaccurate data: 12.13 cm, 9.77 cm, 11.26 cm, 13.55 cm
b. Precise but inaccurate data: 7.36 cm, 7.39 cm, 7.32 cm, 7.35 cm
c. Precise and accurate data: 10.61 cm, 10.65 cm, 10.63 cm, 10.64 cm

#### Work Step by Step

Accuracy refers to the closeness of a measured value to the true measurement or target. In this example, a set of data close to 10.62 cm will be accurate.
Precision refers to the closeness of two or more measurements to each other. For example, the following set of data is precise since the values are close to each other: 7.36 cm, 7.39 cm, 7.32 cm, 7.35 cm.
To get imprecise and inaccurate data, the data has to be very far from the desired outcome and not close to each other. For example the following set is both imprecise and inaccurate 2.13 cm, 9.77 cm, 11.26 cm, 13.55 cm.
To get both precise but inaccurate data, the data has to be far from the target but close to each other. For example: 7.36 cm, 7.39 cm, 7.32 cm, 7.35 cm.
To get data that is both precise and accurate, the data must be very close to the target and close to each other. An example is 10.61 cm, 10.65 cm, 10.63 cm, 10.64 cm.
