The fit order item can be examined based on the values of Infit

Mnsq, Outfit Mnsq, Outfit Mnsq, and Point Measure Correlation

(Sumintono & Widhiarso, 2015). The provisions for reviewing the

suitability of the fit item or non-conformity of the fit item are that the

Mnsq value is at 0.50 - 1.5, or if the score is close to 1, it will be better.

The Zstd value is -2 – (+) 2, or the closer it is to 0, the better. Meanwhile,

the Point Measure Correlation has values ranging from 0.40 to 0.85.

However, if one of these conditions is met, the item can be considered fit

(Bond & Fox, 2015; Sumintono & Widhiarso, 2015; Yudiarso, 2023).

Table 18 shows that all items meet all criteria, except "introductory

paragraph", “cohesion”, and “grammar”. However, they meet three other

three criteria. Overall, it can be concluded that all the analytical assessment

rubric items for argumentative text writing skills are said to be fit, which
