Question

In an experiment to determine the effects of low-dose analgesia versus high-dose analgesia in arthritis sufferers, the following findings are reported: ‘there was a significant effect of low-dose analgesia on pain control F(2, 18) = 8.14, p < .05, = .72’. What does this tell you about the result?

That the probability of a patient suffering pain with low-dose analgesia is high in the population

That the probability of a patient suffering pain with low-dose analgesia is low in the population

That low-dose analgesia is unsuitable in controlling the pain for sufferers of arthritis in this sample

That low-dose analgesia is highly suitable in controlling the pain for sufferers of arthritis in this sample

Explanation / Answer

since p-value is less than 0.05 ( the level of significance), the result tells that the probability of a patient suffering pain with low-dose analgesia is high in the population
