Research Methods: Within Subjects Experimental Designs and Descriptive Statistics Discussion

ResearchMethodswk7.docxFor each DQ elaborate within 250-300 words. Use only reference(s) link(s) provided.
DQ 1) Suppose that, for a t-test, your computed value for t is +3.28. The critical value of t is +2.048. Explain what this means. Do you reject the null hypothesis or not? Now suppose that you have 28 degrees of freedom and are using a two-tailed (nondirectional) test. Draw a simple figure to illustrate the relationship between the critical and the computed values of t for this result.
DQ 2) Choose an article from the newspaper, an online source, or a magazine, then identify the descriptive statistics included in the article. Were the statistics appropriately described in the article? Explain. Discuss if the descriptive statistics used in your source supported the arguments made in it. Were the descriptive statistics misleading? Explain.
