tentative explanation is known as ?

It could be either a theory or hypothesis, depending upon whether it's testable.

The tentative explanation is known as a hypothesis. A hypothesis is a statement that proposes a possible explanation or prediction for a specific phenomenon or problem. It is an educated guess or a starting point for scientific inquiry.

To develop a hypothesis, you need to:

1. Identify the problem or question: Clearly define the issue or topic you want to investigate.

2. Conduct background research: Gather information about the topic to understand existing knowledge and identify any gaps.

3. Formulate an explanatory statement: Based on your research, propose a possible explanation or prediction that can be tested through experimentation or observation.

4. Make it testable: Ensure that your hypothesis is specific, measurable, and falsifiable, meaning that it can be proven false, if necessary.

Once you have a hypothesis, you can proceed with designing experiments or collecting data to test its validity. The results of these tests will either support or reject the hypothesis, leading to further refinement or the development of new hypotheses.
