A hypothesis is a tentative statement about the relationship between two or more variables . It is a specific, testable prediction about what you expect to happen in a study.
Why do we say that an explanation is tentative?
Why do we say that an explanation in science is “tentative?” [Something like:] Because new data/information may not fit previous explanation, so new one must be developed . ... A theory is a much better established explanation, based on tested hypotheses, and more observations.

What do you call your tentative answer?

What does tentative hypothesis mean?

- Complex Hypothesis.
- Null Hypothesis.
- Alternative Hypothesis.

- Statistical Hypothesis.
Is a hypothesis a prediction?
defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction . Rather, a prediction is derived from a hypothesis. A causal hypothesis and a law are two different types of scientific knowledge, and a causal hypothesis cannot become a law.
Is a hypothesis a theory?
A hypothesis is an educated guess or prediction about the relationship between two variables . ... But, because theory is a result of scientifically rigorous research, it is more likely that the theory is true (as compared to a single hypothesis).
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.
What is a good sentence for hypothesis?
Their hypothesis is that watching excessive amounts of television reduces a person’s ability to concentrate . The results of the experiment did not support his hypothesis. These example sentences are selected automatically from various online news sources to reflect current usage of the word ‘hypothesis.’
How do we write a hypothesis?
- Don’t just choose a topic randomly. Find something that interests you.
- Keep it clear and to the point.
- Use your research to guide you.
- Always clearly define your variables.
- Write it as an if-then statement. If this, then that is the expected outcome.
What must a hypothesis be to be valid?
1. The most essential condition for a valid hypothesis is that it should be capable of empirical verification , so that it has to be ultimately confirmed or refuted. Otherwise it will remain a proposition only.
