They found significant differences in difficulty between 3- and 4-, and between 3- and 5-option versions of the three tests adapted to produce the different option versions, but found no differences between the 4- and 5-option versions.
They also found no significant differences in the discrimination coefficients of the different option versions, but for two of the three tests used they found the 3-option version to be significantly more reliable than the 4-option version, while for the third test they found the 5-option test to be more reliable than the 4-option test.
Notably however the distributions of performing sets between the items was not consistent as reflected by the correlation coefficients between the data sets shown in Table 10, none of which were significant and for the reading section, were in two out of three cases, negative suggesting that it was not the same items which were producing the performing sets in the different option format groups.
Therefore, in order to compare the performance of the different option formats in spreading the test taker's option selections, the AENO values were converted to a common scale based on the 4-option values by deducting the mean value of each of the 3- and 5-option sets from each value in those sets then adding back the mean value of the 4-option set.
