Supplementary Data on Math Anxiety and Skills in Brazilian First Graders

229 Brazilian first-grade students participated in a study assessing 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, contains supplementary material for the research paper. It includes results from assessments of math anxiety, mathematical skills, nonverbal reasoning, and language abilities.

Use Cases

• Analyze the relationship between math anxiety and specific symbolic math skills like number production and comprehension.
• Investigate the differential impact of anxiety on calculation versus number sense tasks in young children.
• Model the influence of covariates like nonverbal reasoning and language skills on mathematical performance.
• Replicate or extend regression analyses on the selective effects of math anxiety in early elementary school.

Strengths

• Dataset is based on a study with 229 participants, providing a substantive sample size.
• Research design controls for multiple variables including nonverbal reasoning, language skills, age, and gender.
• Uses standardized assessments like Zareki-R and EES-AMAS, suggesting methodological rigor.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The primary data file is a 662.6 KB DOCX document, which may require extraction or conversion for analysis.
• Data reflects a specific geographic and age-group bias, focusing on Brazilian first graders.
