Here's why:
* Hypothesis: A hypothesis is a testable prediction about the relationship between variables.
* Variables: Variables are factors that can change or vary in an experiment.
* Independent variable: The variable that is manipulated or changed by the researcher.
* Dependent variable: The variable that is measured or observed in response to changes in the independent variable.
Example:
Hypothesis: Increasing the amount of fertilizer will increase the height of tomato plants.
Variables:
* Independent variable: Amount of fertilizer
* Dependent variable: Height of tomato plants
By formulating a hypothesis, you are essentially identifying the variables you will be working with in your experiment.
