Question.4750 - 01143000Here we discuss t-test, p-values, and the limitations of null hypothesis testing. This will be a detailed discussion worth 10 points so plan accordingly.Find, cite, and explain one research article in your field of interest which uses any of the t-tests (one-sample, dependent samples, independent samples) t-test as one of its analysis. One search method is to use the keywords "your topic of interest" and "name of t-test" as in "ADHD independent samples t-test" or "Attention span dependent samples t-test". Use your favorite journal search engine and Google in conjunction. Pick the most recent article.Explain the purpose of the article and the hypothesis which the t-test evaluatesFind and list the APA formatted t-test values as shown in the results sectionExplain what those test results demonstratedReport whether Cohen's d or some other measurement of effect size was reported along with the t-test values? Explain if any other information such as confidence intervals were mentioned. All "point-estimates" like averages, or t-test values can be accompanied by range estimates such as confidence intervals and should be accompanied by measures of effect size. Define p-values and explain your understanding of them. List any questions you might haveExplain your understanding of the limitations on using p-values and null hypothesis testing as found in our unit's required websites and readings.** The main post should be at least 500 words and could be significantly longer this unit, so take your time and write to explain these ideas to yourself and others. Please reply to at least 2 classmates and each reply should be 200 words or more. Remember that we are using discussions and SPSS instead of hand calculations and extensive testing so we expect very strong participation in the discussions and extensive main posts and replies. Post sooner rather than later to give people a chance to see your replies. Help each other answer questions. **
