  1. Unweighted MNSQ is more sensitive to outliers, but weighted MNSQ has more of an impact on instrument functioning. Underlined numbers indicate those outside of the most conservative range (0.7–1.3) but within the less conservative range (0.5–1.5) of MNSQ values. Italic numbers indicate those outside of any acceptable MNSQ range and are considered to have poor fit
