Self-Study: Comparison of Means, Comparison of Means, Part II: ANOVA and Kruskal Wallis
Throughout the course, there will be a self-study Discussion pertaining to an important concept or topic covered within the assigned week. These Discussions are designed to give you the opportunity to collaborate with your peers and faculty, test your knowledge, ask questions, practice research analysis, and assist your peers.
You are not required to post to this forum; however, you are encouraged to post, review the posts of others, as well as answer questions and/or provide clarity and collaboration with your peers. Discussions will be graded as either Complete or Incomplete.

Use this Discussion to collaborate with your peers and faculty as an open office hours/ Q&A forum.
Post answers to the following:
· Summarize the ANOVA or the Kruskal-Wallis output after completing the self-learning module and completing the Required Readings.
· Turgut and Yıldız (2023) used both a
t test and an ANOVA and presented these findings in Table 2 on page 5.
· Compare and contrast the comparisons for the impact of
duration of work on the unit, on the Texas Revised Inventory of Grief (ANOVA), and the
education on terminal period and grief (
t test).
· Were these the correct tests to be used in these analyses? Explain why.
