A team assignment, we were asked to answer the first question about the ethical vignette provided in the assigned text. I was responsible for part c, while I also edited and organized the contributions from other team members. (For privacy reasons, I've only included the initials of my teammates.)
QNT/ 575 Measurement, Evaluation, and Ethics in Research
Hi! This section includes selected assignments that I feel best represent my learning. Feedback appreciated.
This was a team project, and I contributed to all of it except for the sections 'Three Issues for a Research Project' and 'Correlation and Analysis.' I love math, which includes stats! I worked hard to learn how to create unique tables using the National Center for Education Statistics (NCES)'s Common Core of Data database, with tutorial assistance from NCES education statistician Patrick Keaton - thanks again! :)
This is the source for the data that I used as part of my contribution to the team's paper; it includes the original data, which was then parried down and isolated to complete the correlation table - my first correlation table! :) Here's the source info. for the original data: U.S. Department of Education, National Center for Education Statistics (NCES), Institute of
Education Sciences (IES). (n.d.). Public elementary/secondary school universe survey [Common Core of Data (CCD), Build a Table (using the 2008-09 dataset)](v.1b). Retrieved from http://nces.ed.gov/ccd/bat
We had three inferential statistics instruments to choose from for our final paper: t-test, correlation, or chi square analysis. You can't do a t-test if the variables are related. As for the chi square analysis, I couldn't figure out how to derive the Expected value - until the last day of class! So based on another team's data, I spent the afternoon playing with chi square analyses using the other team's original data source. Source for the data is: Cataldi, E. F., Laird, J., KewalRamani, A., & Chapman, C. (2009). High school dropout and completion rates in the United States: 2007: Compendium report (IES 2009-064). Retrieved from U.S. Department of Education website: http://nces.ed.gov/pubs2009/2009064.pdf
We were instructed to create a short mock survey, then to analyze the results. Mine focuses on online learners and their perceptions of the web-based classroom.
