Identify the appropriate statistical test for each research description:

  1. Single-sample z-test

  2. Single-samplet-test

  3. Independent samples t-test

  4. Related samples t-test (repeated measures or matched samples)

  5. Correlation

A researcher would like to determine whether an over-the-counter cold medication has an effect on mental alertness. A sample of n = 16 participants is obtained, and each person is given a standard dose of the medication one hour before being tested in a driving simulation task. For the general population, scores on the simulation task are normally distributed with μ = 60 and σ = 8. The individuals in the sample had an average score of M = 56.5 with s = 9.21.

A researcher conducts a single-sample t test and finds statistical significance at the 0.01 level. The effect size is then calculated and found to be 0.50. What might you conclude about the findings? A. These findings are exciting because statistical significance was found with a very small effect, indicating that the results are real and the chance of a Type I error are low. B. While the results of the test are statistically significant, the effect size indicates that they...
