Measuring Numeracy in a Community College Context: Assessing the Reliability of the Subjective Numeracy Scale

In this paper, our goals were to assess the suitability of the Subjective Numeracy Scale (SNS), developed for health-care use, in a new context with predominantly minority students at a South Bronx community college and to identify any race/ ethnicity, gender, and ESL enrollment effects. The scale assesses perceptions of quantitative reasoning skills and preferences for data presentation. This scale was given to a convenience sample of students in behavioral sciences classes. Results show that the SNS scale was reliable with our sample using the full thirteen-question scale or the shorter eight-item version. Gender, race/ ethnicity, and English as a Second Language (ESL) are related to perceptions of QR/QL. This study may help researchers see the SNS as a reliable instrument across samples and as a way to measure numeracy. The results of the multivariate analyses raise questions for future research about cultural differences for numerical presentation among these ethnic groups and our international student population
