QUESTIONS WITH ANSWERS GRADED
A+
◍ Topic.
Answer: the general subject of the the text
◍ Main idea.
Answer: the key message or thesis of the text
◍ Key points.
Answer: key points and their supporting details develop the main idea
◍ What is the primary difference between parametric and nonparametric
tests?.
Answer: Parametric tests assume specific distributions (like normal), while
nonparametric tests make no strict distribution assumptions.
◍ What are three reasons to choose a nonparametric test?.
Answer: They work for non-normal data, they work for ordinal data, and
they use less information.
◍ What parameter is tested in a Sign Test?.
Answer: The median.
◍ How are ties handled in the Sign Test?.
Answer: Ties are ignored.
◍ Summary.
Answer: a brief restatement of the main idea and the most important key
points and details
◍ What is the test statistic 'x' for a two-tailed Sign Test?.
Answer: The minimum of the number of positive signs and the number of
, negative signs.
◍ What is the underlying distribution for the Sign Test statistic X?.
Answer: Binomial(n, 0.5), where n is the number of non-ties.
◍ Inference.
Answer: a conclusion reached by critical thinking, reading between the
lines, applying logic to facts and evidence while recognizing context clues
◍ How do you calculate the p-value for a two-tailed Sign Test?.
Answer: Multiply the probability of the smaller side by 2: 2 * P(X ≤ x).
◍ What does the Mann-Whitney test evaluate regarding two distributions?.
Answer: Whether the distributions are identical or shifted.
◍ What are the two main assumptions for the Mann-Whitney test?.
Answer: Independent samples and similar shape distributions.
◍ Inference (explicit).
Answer: clearly stated
◍ How are tied values handled when ranking data for the Mann-Whitney test?.
Answer: Ties are assigned the average of the ranks they would have
occupied.
◍ What is the decision rule for the Mann-Whitney test?.
Answer: Reject H0 if the calculated U is less than or equal to the critical
value.
◍ Why does a smaller U value in the Mann-Whitney test suggest a significant
result?.
Answer: A smaller U indicates more separation between the two groups.
◍ Which test should be used if the research question involves comparing the
medians of two groups?.
Answer: The Sign Test.
◍ Which test should be used if the research question involves comparing two
independent groups?.
, Answer: The Mann-Whitney test.
◍ Which test should be used if the research question involves comparing three
or more groups?.
Answer: ANOVA.
◍ Inference (implied).
Answer: implied; not directly stated
◍ What post-hoc test is used after an ANOVA to determine specific group
differences?.
Answer: Tukey's test.
◍ Conclusion.
Answer: a deduction made about an unstated outcome based on prediction,
details, evidence, and results
◍ Descriptive.
Answer: includes sensory details to create a clear mental picture for the
reader
◍ How do you interpret Tukey's test results regarding letters?.
Answer: Same letters indicate no significant difference; different letters
indicate a significant difference.
◍ Expository.
Answer: informs, explains, or tells how to do something; uses only facts and
examples
◍ How do you interpret a confidence interval in the context of significance?.
Answer: If the interval includes 0, the result is not significant.
◍ Narrative.
Answer: tells a story to entertain, inform, or challenge
◍ Persuasive.
Answer: includes facts and strong opinions to make the reader feel, think, or
behave a certain way
