Question: In a correlation test, what is the statistical rule for evaluating a pp-value that is greater than the alpha threshold? State the decision to be made regarding the null hypothesis and the conceptual conclusion regarding the population relationship.

Sample answer: When testing a correlation coefficient, if the pp-value is greater than the alpha threshold, the researcher should retain the null hypothesis. This indicates that the result is not statistically significant, meaning the sample does not provide enough evidence for a relationship in the population.

Key points:

  • Retain the null hypothesis if the pp-value is greater than the alpha threshold.
  • Identify that the correlation result is not statistically significant.
  • Conclude that the sample lacks sufficient evidence of a relationship in the population.

Rubric: Grading Criteria: - 1 point for stating that the null hypothesis must be retained when the pp-value is greater than the alpha threshold. - 1 point for indicating that the result is not statistically significant. - 1 point for concluding that the sample does not provide enough evidence for a population relationship.
