Article critique :(follow the format and also number each one ) for the article: —Mueller and Oppenheimer (2014) The Pen is Mightier than the Keyboard https://journals.sagepub.com/doi/abs/10.1177/0956797614524581 1) Complete APA reference 2) research question and hypothesis- 3) research type (e.g. experiment, survey, participant, observation) 4) description of participants and sampling technique- 5) measurement and procedure- 6) brief results- 7) your evaluation of the research – including at least 1 criticism,1 positive comment- Exercise questions: 1) For each of the following variables, identify the level of measurement, and suggest what measure of central tendency and dispersion might be appropriate to use in its description: A. birth order (oldest to youngest) B. weekly income (dollars) C. political party (membership) D. marital status E. age (years) F. occupation G. hours worked per week H. job satisfaction I. level of education J. body temperature K. ratings of happiness on a scale of 1 to 7 2) An investigator compares the sexual satisfaction of men who have used Viagra for one year with men who have not. At the end of the year, she finds that the Viagra group is significantly more satisfied (at the .05 level) than the other (no Viagra group). A. State the null hypothesis and the alternative hypothesis. B. What would be the Type I and the Type II errors? (state explicitly) C. If the experimenter had used .01 as her required significance level, would the probability of a Type II error have changed? In what way? D. List any potential problems there will be in interpreting the findings from this study. 3) You conduct a study on young, middle-aged and older adults reading comprehension. You measure reading comprehension with a standardized test, where the highest score is 50. The mean comprehension scores are 35 for the young, 45 for the middle-aged and 38 for the old. An ANOVA on these scores yields an F of 4.58, p=.012. A. What can you conclude from this finding? B. After running the ANOVA, you conduct t-tests on pairs of groups and get the following results: Young versus Middle-aged: t(28) =3.98, p=.02 Young versus Old: t(28) =1.25, p=.11 Middle-aged vs. Old: t(28) =3.21, p=.07 What can you conclude from these findings? 4) You wonder if there are more women in the field of psychology than in other social sciences, so you conduct a survey of faculty at southern California colleges to find out. Of 150 professors who responded, you get the following breakdown: Psy Anthro Soc Male 15 25 40 Female 35 25 10 —- —- —- 50 50 50 = 150 Total A. What statistic should you use to analyze this information? B. If it is significant, what can you conclude
