q2 i? Number naming and number comparison correlated significantly, but correlations between number line estimation (PAE) and the other two tasks were no longer significant after Bonferroni correction. → Praet 2013

Bivariate correlation analysis (Table 1) among the three estimation tasks in the kindergarten sample; the authors conclude the tasks "can better not be combined into composite scores".

"Number naming and number comparison tasks correlated significantly, but the correlation between number line estimation (PAE) and number comparison and number naming were no longer significant with the Bonferroni correction"

Discussion¶

Related Claims¶

• Number naming and number comparison are better predictors of kindergarten arithmetic than number line estimation — related
• Symbolic numerical magnitude comparison has a more unique association than number line estimation with children's speed on indirect-addition subtraction items — related
• Both symbolic and nonsymbolic magnitude processing correlate with subtraction accuracy, but subtraction speed is associated only with symbolic tasks — related
• Number line estimation and numerical magnitude comparison correlate with mathematics achievement (r = .24 to .44), with number line estimation more strongly related in older children — reports the opposite
• Symbolic number comparison accuracy is the only number sense measure with a significant partial correlation with math — related
• The association between numerical magnitude processing and subtraction is more prominent for items eliciting indirect addition than for direct subtraction items — related
• Numerical magnitude processing is significantly associated with children's mental multi-digit subtraction performance, controlling for intellectual ability and motor speed — related
• The relation between kindergarten spatial orientation and arithmetic is partially mediated by number line estimation — related
• Fraction magnitude comparison correlated with general math achievement only in the U.S. samples, indicating number line estimation and magnitude comparison tap partly different aspects of fraction magnitude understanding — related
