double number line diagrams
A graphic diagram that shows a proportional relationship between two quantities.
equivalent ratios

data gaps
A part series of observations, measurements, facts, or information that is lacking data.
independent variable
A variable whose variation does not depend on that of another.
mean
A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.
