To prepare for this Assignment: Review the Learning Resources as well as the SPSS resources found in this week’s Learning Resources. Review, download, and install the SPSS software on your computer using the IBM SPSS Installation and Registration document for PC or for MAC in this week’s Learning Resources. Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in this week’s Learning Resources and then choose two variables that interest you. For this Assignment: Write a 1- to 2-page summary and include the following: Early in your Assignment, when you relate which dataset you analyzed, please include the mean of the following variables. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1Par1Edu. A description of what the each of the variables measure. A description of the unit of analysis. A description and explanation of the levels of measurement for each variable (i.e., nominal, ordinal, interval, ratio). Explain how you might conceive these variables to be used to answer a social change question. What might be the implications for social change? Support your summary using appropriate scholarly citations and references. Use proper APA format.

Attached are the two worksheets I need completed Correctly!! Let me know if anyone is able to complete. Thanks

Hypothesis testing is the foundation of conducting research in psychology. Researchers must first determine the question they wish to answer and then state their prediction in a null hypothesis and an alternative hypothesis. Once the hypotheses are stated, researchers move on to data collection. However, once the results come in, the real challenge is to determine if they have meaning; that is, are the results statistically significant or just due to random variation? This application will allow you to practice hypothesis testing by using z-scores to compare a single score to a population mean in order to determine if results are statistically significant. Scenario: Lucy wants to know how her fourth-grade daughter, Monica, scored on a test of reading comprehension compared to the population of other fourth graders in the school district. Luckily, Lucy has taken this course and knows that a z-score will help her understand Monica’s reading score in relation to the population. You can find the data for this Assignment below:Data Set: Monica’s reading comprehension score = 61 Mean fourth grade reading comprehension score = 54 Standard deviation of the fourth grade’s reading comprehension = 2.4 Monica’s z-score in math = 1.10 Mean fourth grade math score = 151 Standard deviation of the fourth grade’s math scores = 12.2 To complete this Assignment, submit responses to the following: State the dependent variable. A dependent variable measures the behavior or attitude of a participant and depends on the participant’s reaction to a condition, or the category of the independent variable that creates the situation under which participants are studied (Heiman, 2015). In this scenario, the dependent variable is Monica’s test scores because they depend on her reaction to the independent variable, which in this case are her reading and math tests. PLEASE CHECK MY ANSWER2. Explain whether Lucy should use a one-tailed or a two-tailed z-test and explain why. A one-tailed test is preformed when you want to predict that the dependent scores, in this case Monica’s test score, will only increase or will only decrease (Heiman, 2015). A two-tailed test is used when you do not predict whether dependent scores will increase or decrease Heiman, 2015). Since it is not indicated in this week’s instructions that Lucy did or want to make any predictions about Monica’s tests score and a , I suggest that she use a two-tailed test z-test. PLEASE CHECK MY ANSWER3. State the null hypothesis in words (not formulas).4. State the alternative hypothesis in words (not formulas).5. Calculate the obtained z-score by hand. Describe your calculations (i.e., show your work).To obtain Monica’s z-score for reading, I had to subtract her raw reading comprehension score of 61 by the mean of all fourth grade reading comprehension scores , which is 54. Then I divided the difference of 7 by the standard deviation of the fourth grade’s reading comprehension, 7 divided by 2.4 is 2.92, which brings me to the conclusion that the z-score for Monica’s reading comprehension is positive 2.92 and it fall above the mean by 2.92 standard deviations (Heiman, 2015).Z= (61-54)/2.4Z= 2.92PLEASE CHECK MY ANSWER6. When alpha is set at .05, the critical value is ± 1.96. Should the null hypothesis be retained or rejected? Explain why. When alpha is set at .05 and the critical value is negative or positive 1.96, the null hypothesis should be rejected because.......THIS IS NOT ANSWER, I TRIED TO UNDERSTAND THIS BUT I AM LOST7. Are the results statistically significant? How do you know?8.What should Lucy conclude about Monica’s reading comprehension score in comparison to the population? PLEASE FULLY EXPLAIN ALL CALCULATIONS AND ANSWERS TO QUESTIONS
