final memo

you have learned a lot about Rasch measurement. For this final project I would like you to put all the pieces together (you have been doing this in your memos already).

Q1) Pretend you had to explain the importance of careful measurement to a friend. Please provide a 1-2 page double spaced explanation as to what you would tell your friend.

Q2) Rasch measurement helps one confront many issues that were ignored in the past by those evaluating test and survey data. Pretend you were now explaining to your friend what were the problems of the old ways of evaluating tests and surveys before Rasch. Please provide a 1-2 page double spaced explanation as to what you would tell your friend.

Q3) If you were evaluating a data set from a test or a survey, and you wanted to write up your results for publication in a journal, what would be the key points of your Rasch analysis that you would want to make. What analysis would you conduct. What aspects of your Rasch analysis would you report? What tables and figures would you use? Please provide a 1-2 page double spaced explanation.

Q4) For the memo you have just completed I asked for you to find a number of Rasch articles that were published. What I would like you to do is to search for 3 Rasch articles that have appeared that consider an issue of importance to education. Also I would like you to find 3 Rasch articles that consider an issue in medical research. Please provide the title and data of the article. Also provide 2-3 sentences summarizing the goal of the article. These would be articles you did not mention in your recent memo.
