Re: Could be humbling
"That's not the error rate, it's an irrelevant statistic for the gullible. The error rate runs between 2 and 30% depending on the board and examination."
You were wrong when you first claimed it, now you're just straight up lying. The error rate is the proportion of errors in the entire sample, ie. all exams that were given a mark. What you are whining about is the proportion of grades that were appealed because there was reason to suspect an error occured, in which the appeal was subsequently upheld. Obviously that is much higher because the vast majority of marks are not suspected to have significant problems. In addition, it's already been pointed out that even that percentage has not ever reached 30% so you should probably stop repeating it.
"No, the marking scheme is objective and markers are moderated. Few, if any, appeals should be successful."
That's just plain stupid. Ideally all appeals should be successful because people would only appeal when there has actually been a problem. As it is, some appeals are unsuccessful because people aren't always correct about that. What you actually mean is that because marking is moderated, the overall error rate should be low and few appeals should be successful compared with the total number of grades given, ie. it should be in the region of 0.04% rather than 30%. Which it is.
