# Hypothesis Testing Matrix

### Create a matrix to test your solutions.

Hypothesis Testing Matrix tool ranks competing hypotheses by the least inconsistent evidence.

Consistent evidence proves nothing, since it can support multiple hypotheses. Consistent evidence does not provide diagnosticity. In-other-words, consistent evidence does not help you choose which path to take.

The Hypothesis Testing Matrix is a simple matrix with your evidence listed down the left-hand column and your different hypotheses going across the top (see the diagram below).

Step 1:  First, you need to generate a number of plausible hypotheses. For help, see Hypothesis Generator, Multiple Hypothesis Generator, and Rival Hypotheses tools.

Step 2:  List your hypotheses in the columns across the top of the form (shown below).

Step 3:  List your significant evidence down the left-most column. Evidence is information that can either support or refute your hypotheses.

Step 4:  Test the evidence for its consistency with each hypothesis. Use “C” for consistent, “I” for inconsistent, and “?” for ambiguous.

Step 5:  You can reset the matrix by rewriting your hypotheses. You can also add new evidence or new hypotheses.

Step 6:  Delete evidence that is 'consistent' with all hypotheses.

Step 7:  Re-evaluate and confirm the validity of inconsistent evidence.

Step 8:  Rank hypotheses by the weakness of the inconsistent evidence. In-other-words, the hypothesis with the least inconsistent evidence is the best one.
