LectureNotes said this term is used to describe what is measured when environmental variables are actively manipulated.

Answer:
The term you’re describing is “dependent variable.” In scientific experiments, the dependent variable is what researchers measure to assess the effect of changing environmental or independent variables. Here’s a detailed explanation:

Independent and Dependent Variables:

In an experiment, there are two primary types of variables:

  1. Independent Variable: This is the variable that the researcher manipulates or changes to observe its effect on another variable. It’s called “independent” because it’s not affected by other variables in the experiment.

  2. Dependent Variable: This is what is measured and affected during the experiment. As the independent variable is manipulated, the dependent variable is observed to see how it responds. The dependent variable “depends” on the changes made to the independent variable.

Example:

Imagine you’re conducting an experiment to determine how different amounts of sunlight affect plant growth.

  • Independent Variable: The amount of sunlight each plant receives.
  • Dependent Variable: The growth of the plants, measured by height, number of leaves, etc.

Solution By Steps:

  1. Identify the Independent Variable:

    • Determine what you will change or manipulate in your study.
    • Example: The duration of sunlight exposure.

  2. Identify the Dependent Variable:

    • Determine what you will measure or observe.
    • Example: The growth measurements of the plants.

  3. Control Variables:

    • Ensure all other variables that could affect the outcomes are kept constant.
    • Example: The type of plant, soil quality, water amount, etc.

Conclusion:

In the context provided by LectureNotes, the “term” you’re looking for, which describes what is measured when environmental variables are actively manipulated, is the dependent variable. Understanding the relationship between independent and dependent variables is crucial for designing effective experiments and accurately interpreting results.

Final Definition:

Dependent Variable: The variable being tested and measured in an experiment, which is affected by changes in the independent variable.
