STA 463 Regression Analysis Course Project 2 Purpose of Project The goal of this project is to perform a thorough multiple linear regression analysis on a data set you collected or choose from a reliable resource. Your final project products include a written project report and an audio-recorded slides presentation. As a result of the survey outcomes I did in IC 17, this project can be completed on your own or in a group with up to three members. In this project, you are expected 1) to synthesize the statistical knowledge you have gained in class and lab, and apply it to a dataset of interest. 2) to identify a research question that can be answered by your dataset, 3) to write clearly about the technical material you have learned. Any data that is suitable for fitting a multiple linear regression (with multiple predictors) and answer your research question would work! 1. Written Report I introduced the structure of a written report back in the description of Project 1. You are expected to follow the same structure when you prepare the project report for Project 2. I allowed people to submit html files that are compiled from RMarkdown for Project 1 report, but for Project 2, I would require all the submitted report to be in word or pdf format. Your written report should be concise. Your report should be no more than 5 pages long (not including references, code, outputs). If you want to include code, do not include it in the body of the report but in an appendix. 2. Slides Presentation I would like to invite all of you to present your project 2 with a slides presentation. You are expected to record a video that introduces your project. You can use any screen cast software to record your presentation as you go through your presentation slides (ppt or pdf slides) and create a video that can be uploaded to YouTube or other websites for me (and other students) in this class to view and evaluate. I have been using a free software, screencast-o-matic for creating class lecture videos. You can probably explore this as a viable option for making such a video. https://screencast-o-matic.com/screen-recorder Your presentation should be at least 4 minutes, and at most 10 minutes. You shall submit both the presentation slides file and the video for this part. Please upload your video to a website and then submit the link to the video webpage in the first page of your presentation slides. 3. Group work statement For those who choose to work in a group project, you will need to elect a group leader. The group leader is responsible for submitting your group project written report and presentation slides/video on CANVAS on behalf of your group and the other group members would not submit anything. But all group members should contribute to the preparation of report, presentation and video. In addition to that, the group also needs to keep a group activity log, as a proof of group member contributions, based on which the group summarizes the contribution of each group member with a 1- page group work statement on the last page of the written report. In the group work statement, I expect to know what group activities were conducted, and which group member contributed to which part in the process. Project Presentation Grading Rubric Category Does Not Meet Expectations Meets Expectations Exceeds Expectations Written report (50%) Description of project/questions is inaccurate or insufficient. Results of statistical analyses poorly described. Conclusions inadequately address questions. Assumptions used in analysis are unstated or invalid. Organization is awkward. Graphical and tabular displays are missing or uninformative. Errors in language mechanics (grammar, spelling) are frequent or serious. Relevant literature citations are missing or inappropriate. Project is introduced accurately. Principal questions, methods and results of analyses (including assumptions), and conclusions addressing client objectives are all clearly stated. Report is organized sensibly and includes appropriate graphical and tabular displays and literature citations. Occasional errors in language mechanics might be present but aren’t distracting. Meets expectations and… Writing is fluid and succinct. Description of methods, analyses, results and recommendations are presented authoritatively and convincingly. Validity of analysis has been evaluated and confirmed. Graphical and tabular displays are well- chosen, carefully formatted and correctly referenced. Errors in language mechanics are rare and minor. Presentation Order of slides is illogical or unintuitive. Many slides are too dense or Slides are logically ordered and mostly uncluttered. Each slide either provides a Meets expectations and… Slides and video (30% for solo project; 20% for group project) incomprehensible. Speaker is difficult to understand, seems unprepared, or answers questions awkwardly. Font sizes and colors make slides difficult to read. Talk is overly detailed and too long, or is underdeveloped and too short. summary or focuses on a single point of discussion. Font sizes and colors are appropriate for presentation media and venue. Presentation is well paced and of appropriate length. Speaker is understandable and well-prepared. Speaker discusses each slide, but does not read from slides. Slides provide a strong introduction, smooth and logical flow throughout, and clear statement of conclusions. Presentation is engaging, polished, and notably enhanced by careful choice of displays and formatting. Communication of results (applies to both written report and oral presentation) (30%) Conclusions are lacking or unclear. Descriptions of statistical procedures are overly technical or missing. Analysis is inadequately connected to the project’s background and needs. Graphical and tabular displays are difficult to read and fail to provide insight into the problem or its solution. Statement of statistical techniques is omitted or described in vague terms. Incorrect notations are used. Conclusions are stated clearly and are connected to the project's original questions. Descriptions of statistical procedures are described at an appropriate technical level. Analyses connect directly to the project’s objectives. Appropriate citations to statistical literature are given. Terminology is used correctly. Graphical and tabular displays emphasize insight regarding conclusions. Meets expectations and… Analyses and descriptions enhance and extend the understanding of the project and its goals. Provides comprehensive, elegant, and well-sourced presentation. Terminology is used precisely. Relevant diagnostics are discussed and interpreted correctly. Group work statement (0% for solo project; 10% for group project) Group work statement clearly introduced the constitution of group members, and role of each member in the project. No log of group activities is provided. Group work statement clearly introduced the constitution of group members, and role of each member in the project. A log of group activities is also attached with a time line. Balanced work load was assigned among the group members. Meets expectations and… Group work statement contains reflections from each individual member about their project collaboration, i.e. procs and cons of the group project format, what would they do differently if they do a group project remotely again, how can they improve their group project work efficiency, etc.
