The performance of 19 impaired and 42 typically developing children was tested using 3 assessment parameters to see which parameter best discriminated between the groups (correctly detected impaired as impaired or typically developing as typically developing). In addition discrimination function analysis was conducted to see which combination of tools provided the best diagnostic accuracy. HOWEVER, the highest Chi-square did not correspond with the highest specificity an
d sensitivity.
As both chi-square and specificity and sensitivity to my knowledge reflect the proportion of participants who are correctly and incorrectly classified, I am struggling to understand this discrepancy.
ANY EXPLANATION would be highly appreciated!!!!!!!!!!!!!!!!!!!!
