A. For every report that uses an index, 100 is the base and demonstrates an even likelihood.

If the index is above 100, this indicates more of a likelihood. If the index is below 100, this indicates less of a likelihood.

There are two ways to interpret a positive index number, either as a decimal or as a percentage:

1. An index of 125 would either be 1.25x more likely or 25% more likely.

2. An index of 245 would either be 2.45x more likely or 145% more likely.
