A linear trend equation is used to represent time series values when the data are changing by equal amounts. This type of equation is particularly useful when the data are changing at a constant rate over time. Percentages and proportions may also be used in some situations, but when the data change by equal amounts, the best choice is to use an equation that accounts for this type of change.
