(12 points; The aim here is to exercise your partnership’s ability to figure out on your own how to use Stata in ways that are unfamiliar to you; therefore: NO consultation with other students allowed for this part of the assignment) This involves the use of the faculty salary data set faculty.dta, which is in the iSite Data tab. For each of questions (a) through (d), do the following: i. In 1 or 2 sentences, briefly summarize how you found the answer. ii. Give a URL or Stata manual-with-page-number or Stata help window or data-analysis-book-with-page-number (or the equivalent) that contains the answer. iii. Run the appropriate command and include the command and Stata output in your write-up. For some of the questions, a graph is produced, and should also be included in your write-up for this assignment. a) How can the Stata pwcorr command be used to find the significance level (i.e., p-value) for the test that the correlation between the variables salary and market is zero? i. Before beginning, we performed a Google search to better understand the correlation between variables. After loading the data file, we then entered the “pwcorr salary market, sig print (.05)” command. The University of Indiana Stata website was very helpful in both providing code and explanations. In this case, the correlation between salary and market test scores was positive, moderately strong, and statistically significant (r=.4072, p < .001). To find the significance...

...STA2300 Data Analysis S1, 14 Assignment 2 Due Date: Weighting: 5 May, 2014 20% Answering the questions in this assignment should not be your first attempt at these types of questions. It is essential that you work through practice exercises from the tutorial sheets and/or text book first. This assignment is important in providing feedback and helping to establish competency in essential skills. Answer all the questions. The questions are not of equal weight; some questions are worth much more than others. The questions relate to material in Modules 1 to 6. Before starting this assignment read Notes Concerning Assignments under the Introductory Material link in the Course Resources Block on the StudyDesk. When you are asked to comment on a finding, usually a short paragraph is all that is required. Do not copy/paste SPSS output into your assignment unless specifically asked to do so. In many cases the SPSS output contains much more information than is required for a correct and complete answer. In those cases just reproducing the output may not attract any marks. Make sure you report only the information from the SPSS output relevant to your answer. In order to obtain full marks for any question you must show all working. Convert your word document to pdf before submission through EASE. See the Introductory Material (Section 5, Assignments) for information about how to do this properly. When submitting this assignment through EASE, name the file as follows: family...
