Question:

A researcher conducts an experiment on human memory and recruits 15 people to participate in her study. She performs the experiment and analyzes the results. She uses a t-test for a mean and obtains a p-value of 0.17.

Which of the following is a reasonable interpretation of her results?

  1. This suggests that her experimental treatment has no effect on memory.
  2. If there is a treatment effect, the sample size was too small to detect it.
  3. She should reject the null hypothesis.
  4. There is evidence of a small effect on memory by her experimental treatment.

Answers

The reasonable interpretation of her results will be:

If there is a treatment effect, the sample size was too small to detect it.
