Basic Chemistry Concepts

Front

What is accuracy?

Back

Accuracy refers to how close a measured value is to the true or accepted value.

Front

What is precision?

Back

Precision refers to how close multiple measurements are to each other, regardless of whether they are close to the true value.

Front

Why is it important for data to be both accurate and precise?

Back

Data that is both accurate and precise increases the reliability of the results and leads to valid conclusions in scientific investigations.

Front

What is an independent variable (IV)?

Back

The variable that is deliberately changed in the experiment.

Front

What is a dependent variable (DV)?

Back

The variable that is measured or observed, which depends on the IV.

Front

What are constants in an experiment?

Back

Variables that are kept the same throughout the experiment to ensure fairness.
