Accuracy vs Precision Quiz

Nora, Abigail, and Grace are conducting a science experiment. They are measuring the length of a standard pencil using a ruler. In this context, what does accuracy mean?

• The total amount of error in their measurement

• The speed at which they take the measurement

• Closeness of their measured value to the actual length of the pencil

• The level of detail in their measurement

Elijah, Anika, and Avery are conducting an experiment in their physics class. They are discussing the importance of precision in their measurements. How would you define precision in this context?

• The degree of exactness or refinement in the measurements they are taking

• The amount of force they apply during the measurement

• The speed at which they take the measurements

• The size of the measuring instrument they are using

James, David, and Hannah are practicing archery. How do accuracy and precision differ in this context?

• Accuracy is how close their arrows land to the bullseye, while precision is how spread out their arrows are from each other on the target.

• Accuracy is how far their arrows land from the bullseye, while precision is how close their arrows are to each other on the target.

• Accuracy is how close their arrows land to the bullseye, while precision is how far their arrows are from each other on the target.

• Accuracy is how close their arrows land to the bullseye, while precision is how close their arrows are to each other on the target.

Lily, Charlotte, and Abigail are conducting an experiment in their physics class. They are discussing the concepts of accuracy and precision. Can you help them understand these concepts with a real-world example?

• Accuracy is like hitting a random spot on a dartboard, while precision is like hitting the same spot on the dartboard multiple times, regardless of where that spot is.

• Accuracy is like hitting the bullseye on a dartboard, while precision is like hitting the same spot on the dartboard multiple times, regardless of whether that spot is the bullseye or not.

• Accuracy is like guessing the weight of a person, while precision is like weighing a person multiple times and getting the same result each time, regardless of whether that result is the person's actual weight or not.

• Accuracy is like hitting the bullseye on a dartboard, while precision is like hitting the same spot on the dartboard multiple times, regardless of where that spot is.

Kai, Abigail, and Avery are conducting an experiment in their science class. They need to provide an example of a measurement that is accurate but not precise. Can you help them?

• Kai measuring the length of his pencil with a ruler that only measures to the nearest inch

• Abigail measuring the volume of her water bottle with a beaker that only measures to the nearest 100 milliliters

• Avery measuring the temperature of the classroom with a thermometer that only measures to the nearest 10 degrees

• Abigail measuring her weight with a scale that only measures to the nearest pound

Arjun, David, and Olivia are conducting an experiment. They noticed that one of their instruments is precise but not accurate. Which of the following could be an example of such a situation?

• Arjun uses a ruler that consistently measures the wrong length, but always measures the same wrong length.

• David uses a scale that consistently shows the wrong weight, but always shows the same wrong weight.

• Olivia uses a thermometer that consistently displays the wrong temperature, but always displays the same wrong temperature.

• They have a clock in their lab that consistently shows the wrong time, but always shows the same wrong time.

Grace, Maya, and Nora are participating in a science experiment. In which situation is it important for them to prioritize accuracy over precision?

• When they are estimating the amount of chemicals needed for the experiment, rather than being precise

• When the experiment requires a high level of precision in measurements but not necessarily accuracy

• When the exact value of the temperature at which a reaction occurs is more important than the margin of error

• When the margin of error in their measurements is more important than the exact value

Sophia, Nora, and Maya are working on a project. In which scenario is it more important for them to prioritize precision over accuracy?

• When they are building a birdhouse for their backyard.

• When they are conducting a chemistry experiment for their science fair project.

• When they are practicing for their school's basketball team.

• When they are baking cookies for a school fundraiser.

Emma, Harper, and Mia are conducting a scientific experiment in their school lab. They are using a measuring instrument that is known to provide precise but inaccurate readings. Explain the impact of this on their experiment.

• Improve the validity of their experiment

• Affect the overall reliability and validity of their experiment

• Have no impact on their experiment

• Increase the accuracy of their experiment

Avery, Zoe, and Arjun are conducting an experiment in their physics class. They are discussing the significance of their measurements being accurate but not precise in their experiment. What could be a possible interpretation of their discussion?

• Accurate but not precise measurements provide a reliable average value without being affected by random errors.

• Accurate but not precise measurements are completely unreliable and should not be used.

• Accurate and precise measurements provide a reliable average value without being affected by random errors.

• Accurate but not precise measurements are affected by random errors and should be avoided.
