Math Anxiety and Skills in 229 Brazilian First Graders

229 Brazilian first-grade students participated in a study examining the selective impact of math anxiety on symbolic versus nonsymbolic mathematical skills. The dataset, authored by Angélica Polvani Trassi and last updated in April 2026, likely contains assessment scores for math anxiety, number sense, calculation, and other cognitive measures. Results indicate math anxiety correlated with lower performance in symbolic skills like number production and comprehension, but not with number sense or calculation.

Use Cases

• Modeling the relationship between math anxiety and specific symbolic math skills based on the described regression analysis.
• Analyzing the differential impact of anxiety on calculation versus number sense tasks as mentioned in the results.
• Investigating the role of covariates like nonverbal reasoning and language skills in early math performance.
• Replicating the study's findings on the selective cognitive demands of math anxiety in young children.

Strengths

• Includes data from 229 participants, providing a substantive sample size for analysis.
• Assessments cover multiple domains: math anxiety, symbolic/nonsymbolic math skills, nonverbal reasoning, and language skills.
• Uses controlled regression analysis, as described in the method, to isolate the effect of math anxiety.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 660.7 KB file size suggests a limited scope, likely containing summary or processed data rather than raw records.
