AEE 521 Basic Applied Data Analysis in Agricultural and Extension Education Assignment - Pennsylvania State University, USA

Problem 1 - Jana heard that the use of social media (e.g. Facebook) during instruction would enhance the learning achievement of students. To test this idea, Jana conducted a study to investigate the effect of a Facebook-based instructional approach on preservice teachers' learning achievement. A pre-test post-test quasi-experimental design with non-equivalent control group (CG) was employed. The effectiveness of Facebook-based instructional approach was assessed against conventional instructional approach for pedagogy of mathematics course in the pre-service teacher education program for their effect on learning achievement of pre-service teachers. Jana wanted to know whether post-treatment learning achievement score of pre-service teachers varied based on what intervention group (Facebook or control) the pre-service teachers belonged to. Jana also collected data from pre-service teachers regarding their pre-treatment learning achievement scores. Now as the main research question, Jana wants to know after controlling for pre-treatment learning achievement score of pre-service teachers, how the post-treatment learning achievement score of pre-service teachers varied based on what instructional group they belonged to. Conduct the appropriate statistical test at ? = .05 using SPSS to answer Jana's questions. Please conduct descriptive analysis, appropriate statistical assumption tests, appropriate test statistics analysis, and calculation of effect size measure. You should write appropriate null and alternative hypothesis. In your response to this problem, please provide a write-up (should include description of results, statistical assumptions, interpretation of findings, and effect size), SPSS output, and SPSS syntax from your analysis. For the write-up, please follow appropriate format from your profession's specific journal. The write-up should be concise containing only what is required. The data from the study are available in the attached AEE521_Problem1_Facebook sav file.

Problem 2 - Joseph is interested in learning more about the famous cruise ship, Titanic, that was sunk in 1912. Specifically, his brain had a few questions, i.e., whether any association existed between the class of the ship people travelled in and their survival and whether any significant differences exist in survival (death or alive) and the class of the ship people travelled in? Joseph reached out to original investigators, who investigated the Titanic ship accident. From investigators, Joseph found that there were 1,309 passengers on the ship. Joseph collected information from investigators what were the different classes (1^st, 2^nd, or 3^rd) people travelled in and which people died, and which survived the accident. Conduct the appropriate statistical test at α = .05 using SPSS to provide answers to Joseph's questions. Please conduct descriptive analysis, appropriate statistical assumption tests, appropriate statistical test statistics analysis, and calculation of effect size measure. You should write an appropriate null and alternative hypothesis. In your response to this problem, please provide a write-up (should include description of results, statistical assumptions, interpretation of findings, and effect size), SPSS output, and SPSS syntax from your analysis. For write-up, please follow appropriate format from your profession's specific journal. The write-up should be concise containing only what is required. The data from the study are available in the attached AEE521_Problem2.sav file.

Problem 3 - Israa read about how a mother's pre-pregnancy weight can affect a baby's birthweight. She conducted a pilot study to test the assertation about the relationship between a mother's pre-pregnancy weight and baby's birthweight and how mother's pre-pregnancy weight predicts baby's birthweight. She collected mother's pre-pregnancy weight and baby's birthweight data from 42 mothers and their new born babies, respectively. Conduct the appropriate statistical test at α = .05 using SPSS to test Israa's assertion described above. Please conduct descriptive analysis, appropriate statistical assumption tests, appropriate statistical test statistics analysis, and calculation of effect size measure. You should also write appropriate null and alternative hypotheses. In your response to this problem, please provide a write-up (should include description of results, statistical assumptions, interpretation of findings, and effect size), SPSS output, and SPSS syntax from your analysis. For write-up, please follow appropriate format from your profession's specific journal. The write-up should be concise containing only what is required. The data from the study are available in the attached AEE521_Problem3.sav file.

Note - The first problem you will solve it using ANCOVA. The second problem you will solve it using chi-square and The third problem you will solve it using correlation.
