class: center, middle, inverse, title-slide # Final Meetup ## DATA 606 - Statistics & Probability for Data Analytics ### Jason Bryer, Ph.D. and Angela Lui, Ph.D. ### May 17, 2023 --- # Final Exam * Is now available on Blackboard. * Due by end of day May 21st. * You may use your book and course materials. * We expect you to complete the exam on your own (i.e. do not discuss with classmates, colleagues, significant others, etc.) * There are two parts: 1. Part one multiple choice questions and short answer questions. 2. Part two has a small data set to analyze with R, then answer some interpretation questions. * Put your answers in the Rmarkdown file and submit the PDF file. **Please do not post your answers online!** --- # Jason's Work <img src="images/hex/psa.png" class="title-hex"> My statistical research interest is in propensity score methods. Propensity score analysis (PSA) is a quasi-experimental design used to estimate causality from observational studies. Here are some resources for PSA: * PSA [Github repository](https://github.com/jbryer/psa) includes slides slides and Shiny application: https://github.com/jbryer/psa * Early version of an [Intro to PSA](https://psa.bryer.org) book: https://psa.bryer.org * Recording of a talk given this semester here: https://spring2023.data606.net/blog/intro_psa/ * I will be teaching a workshop for [Workshops for Ukraine](https://sites.google.com/view/dariia-mykhailyshyna/main/r-workshops-for-ukraine#h.hep5crn3g4pc) on July 6, 2023. .pull-left[ <img src='images/hex/psa.png' height='100' align='left' style='padding-right:20px'> `multilevelPSA`<br/> [Multilevel PSA]((http://jason.bryer.org/multilevelPSA) <br/><br/> <img src='images/hex/TriMatch.png' height='100' align='left' style='padding-right:20px'> `TriMatch`<br/> [Matching with non-binary treatments](http://jason.bryer.org/TriMatch) ] .pull-right[ <img src='images/hex/PSAboot.png' height='100' align='left' style='padding-right:20px'> `PSAboot`<br/> [Bootstrapping PSA](http://jason.bryer.org/PSAboot) <br/><br/> <img src='images/hex/PSAgraphics.png' height='100' align='left' style='padding-right:20px'> `PSAgraphics`<br/> [Graphical analysis of PSA](http://jason.bryer.org/PSAgraphics) ] --- # Jason's Work (cont.)

DAACS provides personalized feedback about students’ strengths and weaknesses in terms of key academic and self-regulated learning skills, linking them to the resources to help them be successful students. Applications of Data Science: * We use natural language processing and predictive models to machine score the essays. * We use DAACS data to estimate "risk scores" for students failing so we can target them with resources to help them be successful. Received a $3.8 million grant this year from the Institute of Education Sciences to test the efficacy at three institutions. --- # Angela's Work: Students’ responses to feedback .center[ <img src="images/Lui_dissertation.jpg" width="800" style="display: block; margin: auto;" /> ] --- # Exploring Responses to Feedback in DAACS **Some Research Questions** 1. What are the sentiments conveyed in students’ essays? 2. What judgments about SRL feedback emerge in students’ essays? 3. What meanings do students make of the SRL feedback? (a focus on the content criterion?) 4. What attributions do students make if any? 5. To what strategies do students tend to commit? 6. Are these (above five bullets) related to 1) the number of dots they received per domain? 2) the number of feedback pages they viewed? 3) the level of feedback specificity they viewed? **Data Sources** * Students’ essays on the DAACS Writing Assessment * Students’ SRL Assessment Results and Feedback **Analyses** * Sentiment Analysis * Content Analysis --- # Thank You This has been a great semester.
