Tests
In the prior question, it was noted that the Relative Risk was 5.0. How
| | | | | | | | | | | | | |
would you interpret this statistic?
| | | |
a) Positive Association; exposed people are at greater risk to the
| | | | | | | | | | |
outcome compare to non-exposed people
| | | |
b) Negative Association; exposed people have a negative experience
| | | | | | | |
