The data for this investigation were the editing markings on the original test items submitted by the teachers. Scores for 9 scales of information were recorded for analysis. Each of the scales was established so that a low score would be optimal. The frequency and percentage of scores for the 993 items on the nine ratings, and mean scores of each factor, are shown in Table 2. An item's SE rating indicates how many words were misspelled in the item.
Spelling errors are detrimental to good teaching and testing.
However the literature shows that this problem is common to other disciplines. There were 993 items. The authors were compared on each of the scales to determine whether they differed significantly and to see if similar or dissimilar errors were made by different authors.
