Dependent Variables

Dependent variables are the outputs or outcomes in an experiment or study. They depend on the independent variables, which are the inputs or factors that are manipulated or changed. The value of the dependent variable is determined by the changes in the independent variable.

Example:

In an experiment to test how the amount of fertilizer affects plant growth, the dependent variable is the height of the plant. The amount of fertilizer (independent variable) is changed, and the resulting growth of the plant (dependent variable) is measured.

Identifying Dependent Variables:

To identify the dependent variable, ask yourself what is being measured or observed in response to the changes in the independent variable. Dependent variables are typically the outcomes, results, or effects of the changes being studied.

Study Guide for Dependent Variables:

Understand the relationship between dependent and independent variables.
Practice identifying dependent variables in various scenarios.
Learn how to design experiments and studies with clear dependent variables.
Understand the importance of controlling for confounding variables when studying dependent variables.

Grade 7 Curriculum Focal Points (NCTM)

Number and Operations and Algebra: Developing an understanding of operations on all rational numbers and solving linear equations

Students extend understandings of addition, subtraction, multiplication, and division, together with their properties, to all rational numbers, including negative integers. By applying properties of arithmetic and considering negative numbers in everyday contexts (e.g., situations of owing money or measuring elevations above and below sea level), students explain why the rules for adding, subtracting, multiplying, and dividing with negative numbers make sense. They use the arithmetic of rational numbers as they formulate and solve linear equations in one variable and use these equations to solve problems. Students make strategic choices of procedures to solve linear equations in one variable and implement them efficiently, understanding that when they use the properties of equality to express an equation in a new way, solutions that they obtain for the new equation also solve the original equation.
