what are the 3 kinds of variable
Answer (1)
1. Independent VariableThis is the variable that you change or control in an experiment.It is the cause or reason for a change.Example: If you're testing how sunlight affects plant growth, the amount of sunlight is the independent variable.2. Dependent VariableThis is the variable that you measure in the experiment.It depends on the independent variable.Example: In the same plant experiment, the growth of the plant (height or number of leaves) is the dependent variable.3. Controlled Variable (or Constant Variable)These are the variables that stay the same throughout the experiment.Keeping them constant helps ensure the results are accurate and fair.Example: The type of plant, the amount of water, and the type of soil should all be controlled.
