In science, data is information collected during an investigation, which can include numbers, symbols, pictures, or text.

A mean average is calculated by adding values together and dividing the total by the number of values.

A line graph is a type of diagram used to show how a variable changes over time.

To plot a mark or line on a graph means to place it correctly on the axes according to its values.
