SI 544 project

You will be working in groups, and will share the same grade with your group members. This project will account for 15 points of your final grade.

The idea is to collect some data and analyze it. You can collect new data (e.g. conduct a survey or an experiment) or get a hold of a previously collected data set (e.g. web server logs, data from a previous study). The hypothesis you test should not have been examined before with regard to that particular data set.

project timeline

due date
turn in on 9/21 along with PS 2

select a project topic and formulate the question you will answer with the data
schedule 20 minutes when all members of your group can discuss your topic with the instructor

collect a preliminary set of data

submit a progress report including
  • 1 page explaining your question and a description of how you are collecting the data
  • a copy of a sample of your preliminary data
  • collect data
  • perform the data analysis

submit a project report including

  • a plot or a group of plots on a single page showing the most important features of your data
  • a summary statistic answering the question you were posing
  • a discussion of your results, including possible sources of bias, hidden variables, etc.
  • if your results were not statistically significant, estimate how large of a data sample you would have needed to get significant results
