Description

In the online class, participation is graded as a part of discussion. In addition to your own post (which is due by Thursday midnight of each week), you should respond to the posts of a peer each week. To be substantive, your reply should add more information to the discussion, bring a helpful resource to the discussion forum, or question the response on the merit of your own research. Posts should be at least 250 words and each reply should be at least 150 words. In order to receive full credit you'll need to reference the content of the discussion to your field of study (ex: nursing). Think about how the concept would apply to your field, how you would encounter the concept in your field, and how you would interact/experience the concept in your field of study.

Instructions:

Visit the following website: http://blog.minitab.com/blog/statistics-and-quality-data-analysis/large-samples-too-much-of-a-good-thing (Links to an external site.)

Researchers may seem to be more often concerned with small sample sizes and tests that, as a result, lack power, yet having a very large sample can create its own set of problems. Speculate these issues by pointing out the relationships between sample size and power when the magnitude of effect is held constant. What other implications can you gain from the information?

Please post your initial response by 23:59 CST Thursday the Week, and comment on the post of a classmate by 23:59 CST Sunday.

Submission Instructions:
Writing should be in APA format (Times New Roman size 12 font). Proofread for grammatical accuracy. Late posts will be deducted points. Late replies will not be counted. Forums will close at 23:59 CST Sunday of each week. Type your response into the forum, avoid uploading a Word document with your post.

Explanation & Answer

hi there here is the assignment please review and let me know if you need edits.

Power is the probability of correctly rejecting the null hypothesis that sample
estimates do not statistically differ between study groups. In studies, researchers hope to
achieve large values of power of at least 80%.In most cases, power is positively
correlated with the sample size. When there is an issue with rese...
