1. Statistically significant and substantive differences between level 1 and levels 2, 3, 4; and between level 2 and levels 3, 4.
2. Statistically significant and substantive difference between levels.
3. Statistically significant and substantive differences between level 1 and level 2, 3.
4. Statistically significant and substantive difference between levels 3 and 4; and between levels 4 and 5.
5. Statistically significant and substantive difference between Newfoundland and Labrador and Manitoba. No other provincial differences were statistically significant at p<0.001.
Notes
Statistical significance: p<0.01 for differences between 2 levels of parent education level, family structure, and country of birth of parent; p<0.008 for differences among 4 levels of household income level (nominal significance level of p<0.05 adjusted for multiple comparisons).
Statistical significance: p<0.005 for differences among 5 levels of community size (nominal significance level of p<0.05 adjusted for multiple comparisons); p<0.001 for differences among 10 levels of province of residence (nominal significance level of p<0.05 adjusted for multiple comparisons).
Substantive differences are defined as mean differences of 0.25 of a standard deviation (0.25 SD) or more, as follows: for receptive vocabulary score at age 5, 0.25 SD=3.84.
Numbers vary due to missing data for some child and family characteristics.
LICO refers to the low income cut-off.
