Front

What is quantitative data?

Back

Quantitative data refers to numerical information that can be measured and expressed in numbers, such as height, weight, or temperature.

Front

What is qualitative data?

Back

Qualitative data refers to descriptive information that cannot be measured numerically, such as colors, textures, or opinions.

Front

What does high accuracy and high precision mean?

Back

High accuracy means the data is close to the true value, and high precision means the data points are close to each other.

Front

What does it mean if data is precise but not accurate?

Back

It means that the data points are close to each other but far from the actual value.

Front

What does it mean if data is both precise and accurate?

Back

It means that the data points are close to each other and also close to the actual value.

Front

What is the difference between accuracy and precision?

Back

Accuracy refers to how close a measurement is to the true value, while precision refers to how close measurements are to each other.

Front

What is an example of high accuracy and low precision?

Back

A set of measurements that are all over the place but average out to the true value.

Front

What is an example of low accuracy and high precision?

Back

A set of measurements that are very close to each other but far from the true value.

Front

What does a bullseye with all darts clustered together but far from the center represent?

Back

It represents high precision but low accuracy.

Front

What does a bullseye with darts scattered all over but averaging to the center represent?

Back

It represents low precision but high accuracy.
