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 medication A (low-dose analgesia) on pain control F(2, 18) = 8.14, p < .05, ω = .72'. What does this tell you about the result?
A) That the probability of a patient suffering pain with low-dose analgesia (medication A) is high
B) That the probability of a patient suffering pain with low-dose analgesia (medication A) is low
C) That low-dose analgesia (of type medication A) is unsuitable in controlling the pain for sufferers of arthritis
D) That low-dose analgesia (of type medication A) is highly suitable in controlling the pain for sufferers of arthritis

Quizplus · Accepted Answer

The finding that there was a significant effect of medication A (low-dose analgesia) on pain control, with a high effect size (ω = .72), suggests that low-dose analgesia is highly suitable in controlling the pain for sufferers of arthritis. The lower the p-value, the stronger the evidence against the null hypothesis, meaning that the probability of obtaining such a result by chance is very low. This result indicates that medication A (low-dose analgesia) is effective in controlling arthritis pain.
