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

Front

What is a pie chart used for?

Back

A pie chart is used to show the proportions of a whole, typically representing percentages of categories.

Front

What is the formula for calculating density?
