Inter item correlation interpretation
WebAccording to Clark and Watson (1995), average inter-item correlations should fall somewhere between .15 and .50 as anything below .15 would be too broad of a construct … WebMar 26, 2009 · The item total correlation is a correlation between the question score (e.g., 0 or 1 for multiple choice) and the overall assessment score (e.g., 67%). It is expected that if a participant gets a question correct they should, in general, have higher overall assessment scores than participants who get a question wrong.
