How are hypotheses tested

collecting data

What kind of reasoning is often used to form theories

A Theory is a hypothesis that has withstood testing, but cannot be proven infallibly true, meaning that the only way to form a theory is through scientific testing. Reasoning is necessary to form a hypothesis, which will be considered a theory once tested and supported by the results. Two types of reasoning are Inductive Reasoning and Deductive Reasoning.

Inductive ReasoningMaking observations and extrapolating to come to a conclusion beyond the scope of current information.

i.e.

The grass outside is green

therefore

All grass is green

Deductive ReasoningUsing logic to reach a conclusion, specifically when the conclusion necessarily follows the premise(s).

i.e.

This mouse is gray

and

All gray mice are fast

therefore

This mouse is fast

Once you have a hypothesis, it can be tested using the Scientific Method.

Scientific Method
  • Ask a question
  • Do background research
  • Construct a hypothesis
  • Test your hypothesis using an experiment
  • Analyze data and draw a conclusion
  • Communicate your results

If the results of the experiment support the hypothesis, then it is considered true. If others are able to duplicate the experiment and achieve the same results, the hypothesis will be considered a theory.
