Re:Topic 3 DQ 1 Z-test is a statistical hypothesis
“Z-test is a statistical hypothesis test that follows a normal distribution while T-test follows a Student’s T-distribution” (Ian, 2010). If a study requires a larger sample such as greater than 30 then a Z-test would be a more appropriate test compared to the T-test. The T-test is better to use for smaller samples. Additionally, if standard deviations (SD) are already known then a Z-test is the better test to use even if it is for a smaller sample. Furthermore a Z-test would be a better test to use if doing a large study on the population whether the SD is known or not. A T-test is easier to use than a Z-test as a Z-test may need specific conditions in order to render a reliable outcome. Generally a T-test is more common to use due to fact that the t-test has different types of methods which can be used in many ways (Ian, 2010).

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.
Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.
The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
Discussion Questions (DQ)
Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation
Your initial responses to the mandatory DQ do not count toward participation and are graded separately.In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality
Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.It is best to paraphrase content and cite your source.
