Sentences with phrase «candidate explanatory factors»

Candidate explanatory factors were chosen on the basis of empirical studies suggesting their potential contribution to the gradient and data availability.2 The ECLS - B data set contains rich longitudinal data on various family, health, and home environment variables, along with direct measures of cognitive abilities at school entry.

Candidate explanatory factors explained just over half of the Q1 — Q5 and Q1 — Q3 SES gaps in children's math ability (57 % and 60 %, respectively).

Candidate explanatory factors explained about half the Q1 — Q5 and Q1 — Q3 SES gaps in reading ability.

Steep SES gradients were apparent across all candidate explanatory factors (Table 1).

This study represents one of the more comprehensive investigations of candidate explanatory factors, yet our analyses explained just over half of the gaps between the highest and lowest, and lowest and middle, SES quintiles with regard to early reading and math scores, suggesting that many additional factors are involved.

Candidate explanatory factors explained just over half the gradients, with family background factors explaining 8 % to 13 %, health factors 4 % to 6 %, home learning environment 18 %, parenting style / beliefs 14 % to 15 %, and early education 6 % to 7 % of the gaps between the lowest versus highest quintiles in reading and math.

A decomposition methodology examined the contribution from different sources in explaining the SES gradient in early cognitive outcomes.34 Similar to the methodology used in the UK Millennium Cohort Study, we focus on the quintile 1 — quintile 5 (Q1 — Q5) and quintile 1 — quintile 3 (Q1 — Q3) gaps and calculate the percentile points and the percentage of the raw gaps explained by each candidate explanatory factor and each domain of factors.2 This was done by taking the product of the mean gap in each explanatory factor (mean difference between Q1 — Q5 and Q1 — Q3) by the β coefficients from linear regression models that predict reading and math ability from SES and all candidate explanatory factors.
