Question:

The hypothetical plots below show the relative frequencies of subjects assigned to two experimental groups (treatment and control). The frequency of negative outcomes (red) and positive outcomes (gold) is illustrated. For each plot (a), (b), and (c), identify the correct value of the odds ratio: 0.1, 0.5, 1, 2, or 9.

Relative frequency 1.0 0.8 0.6 0.4 0.2 0 Treatment Control 1.0 0.8 0.6 0.4 0.2 0 Treatment Control (c) (a)
