Canonical discriminant function coefficients across age groups.

Age group	Constant	Coefficient × (Score)	Cutoff score
Age Group 1 4;0–5;1	−3.236	6.499 × (x)	50
Age Group 2 5;2–5;11	−4.500	5.734 × [arcsine (x)]	70
Age Group 3 6;1–7;0	−3.393	4.392 × [arcsine (x)]	70

Note. The formula used to derive the cutoff score for age 1 is the following:

$$0=\mathrm{constant}+\mathrm{coefficient}(x),$$

where x is the value of the cutoff score. Given the significant differences in equality of variance–covariance matrices for Age Groups 2 and 3, the cutoff scores were derived by using the following formula:

$$0=\mathrm{constant}+\mathrm{coefficient}[\mathrm{arcsine}(x)]$$

The value of x was solved by using the following formula:

$$x=\sin [\mathrm{arcsine}(x)].$$
