> 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.
