Best Dr Nahed Ghazzoul > Date: Mon, 1 Aug 2011 16:25:30 +0100 > From: [log in to unmask] > Subject: The Kappa test > To: [log in to unmask] > > My research involves analysing errors in a learner corpus ( a collection of texts written by English as a foreign language learners). I am sorting the errors into 56 error categories (mainly 8 major error categories): Form, Grammar, lexico grammar, lexis, Word redundant or missing, Style, Infelicities.To ensure reliability, a sample of twenty papers will be analyzed by a second coder. i.e. He will read the text, identify the errors and give them an appropriate tag/code. The second analyst will be given an error tagging manual to guide him in giving the codes. > > The researcher (the first analyst) has used the same manual.The research aims to find the most common and the least frequent errors in these written texts. One of the statistics I need to have using SPSS 16 is: > > I will need to - count how many phrases/words, etc. were considered as errors by both judges (because sometimes one judge doesn't consider something an error, whereas the other does). Once I have a list of these agreed upon 'error tagging targets', Iwill need to do a statistic to assess how much the judges agreed in the error tags they used to code these errors. The test to do is the Kappa test. > > I do not know how to prepare my data for the Kappa test. How many variables I will need? What are these variables?. What would be the count?Could you please provide me with a detailed explanation for my research?
