Original post is due by Friday, April 21. This may be considered a \”rough draft.\” Then review at least one classmate\’s work to point out any errors you can find. You must offer substantive suggestions to at least one other student\’s posts and post any corrections you have to your own by Friday, April 28. In commenting to other students, remember that a simple \”Good job!\”, while nice, does not help the student get a better grade, and will not be sufficient for you to get full credit for this part of the assignment. Neither will comments about how interesting the article is, or how it applies to your life. Concentrate on the work the student has done; your suggestions for revisions will be appreciated by your fellow students!
Be sure to to see the example that I have posted.
Choose a recent research article, preferably published in the last 10 years, from the library\’s databases, or use one of the articles that I posted. Try to choose an article that no one else has chosen. (I realize that more than one student may be simultaneously working on the same article without knowing it, and that will be okay. But if you see that multiple students have already chosen an article, please choose another.) Summarize the research by answering the questions below. Please include a copy of the article as an attached file. Post your summary, then comment on at least one other person\’s post. In your comment, verify if that student\’s interpretation was correct, or if there is something that needs to be corrected. If desired, each student will have until April 28 to make corrections on his or her own report, based on the posts of other students.
Your article must include one of these statistical tests:
z test
single-sample t test
independent samples t test
dependent (paired) t test
One-Way Analysis of Variance
Factorial (two-way) Analysis of Variance
Pearson\’s r (Correlation)
If you want to choose your own article, the best way to do so is to use the library\’s databases. From Lonestar.edu, click on \”LSCS Libraries\” and then on \”Research Databases.\” If you are on an off-campus computer, you will be asked to enter the 14-digit bar code from the back of your student ID or library card. If you do not have a student ID, you may access the databases from a campus computer. (Alternately, I will accept a journal article found on the Internet, for example, through Google Scholar.) Choose the database that you would like to use. I would choose \”Social Sciences\” and then \”Psychology and Behavioral Sciences Collection,\” but you may choose any database that interests you. Once you have chosen your database, search for a topic that interests you. Click on Advanced Search so you can enter your chosen topic and also enter the type of statistic you are looking for (for example, ANOVA) as a separate phrase. To limit your search, check the boxes that limits the results by date (last 10 years) and by availability of the full text. Then skim over the results list until you find an article that seems interesting and somewhat comprehensible. Save this article (or email it to yourself and save) to a file so you can attach it to your post. Then answer the questions below about the article. If there was more than one statistical test performed and reported, just choose one of the more important tests. You do not have to answer the questions for every statistical test that was performed. I have posted an example. In my example, I clicked on Advanced Search and entered two sets of terms: orphans and vulnerable children and ANOVA, both in All Text.
Provide the following information:
1. Citation (You can click on citation and your citation will be properly formatted. If given a format choice, choose APA format. )
2. Summarize the study in one or two sentences:
3. Identify the independent variable(s):
4. Identify the dependent variable:
5. What statistical test was used?
6. State the calculated value of the test statistic, if given. For example, this would be the value of z, t, F, or r. Be sure you are looking at the test associated with one of the main findings of the research. Answer the remaining questions as they apply to this finding only.
7. State the confidence Interval, if given:
8. Was the result statistically significant? Be sure to use the same result as you reported in 6.
9. State the effect size, if given. This might be Cohen\’s d or R2 (sometimes written as 2 or eta squared).
10. What was the p-value (the probability of getting these results by chance)? Make sure this agrees with the results reported in question 8.
11. Write the results in APA format, for example, if you were repor
