  • variables being investigated over time. • Because the year and the population change, they are the variables. The population is determined by, or dependent on, the year. So population is the dependent variable, and the year is the independent variable. • Each set of data is called a data pair. Data pairs are easily organized into data tables.

A key element of this process is the generation of investment projects, defined as an investment of capital to create assets capable of generating a stream of benefits over time. A project may be independent or part of a package of projects comprising an integrated development effort. The process of generating projects is called the project cycle. Dependent variable definition, a variable in a functional relation whose value is determined by the values assumed by other variables in the relation, as y in the relation y = 3x2.
