What is an Ivcdv?
Independent variable and dependent variable.
What are variables in a hypothesis?
Variables are measurable characteristics or properties of people or things that can take on different values. In contrast, characteristics that do not vary are constants. A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data.
What is a variable in a hypothesis example?

What is a good hypothesis example?
Here’s an example of a hypothesis: If you increase the duration of light, (then) corn plants will grow more each day. The hypothesis establishes two variables, length of light exposure, and the rate of plant growth. An experiment could be designed to test whether the rate of growth depends on the duration of light.

- Do Background Research.
- Construct a Hypothesis.
