EdSurvey is an R statistical package designed for the analysis of national and international education data from the National Center for Education Statistics (NCES). The released EdSurvey Version 2.6.9 includes the following data sources:
- National Assessment of Educational Progress (NAEP)
- Trends in International Mathematics and Science Study (TIMSS) and TIMSS Advanced
- Progress in International Reading Literacy Study (PIRLS) and ePIRLS
- International Computer and Information Literacy Study (ICILS)
- International Civic and Citizenship Education Study (ICCS)
- Civic Education Study (CivEd)
- Programme for International Student Assessment (PISA)
- Programme for the International Assessment of Adult Competencies (PIAAC)
- Teaching and Learning International Survey (TALIS)
- Early Childhood Longitudinal Studies (ECLS-K: 1998, ECLS-K: 2011, ECLS-B)
- Education Longitudinal Study of 2002 (ELS)
- High School Longitudinal Study of 2009 (HSLS)
- Beginning Teacher Longitudinal Study (BTLS)
EdSurvey is developed by AIR, commissioned by the NCES. EdSurvey is tailored to the processing and analysis of NCES large-scale education data with appropriate procedures to analyze these data efficiently—taking into account their complex sample survey design and the use of plausible values.
Here is how to get started with EdSurvey:
Installing and Loading EdSurvey
Inside R, run the following command to install EdSurvey as well as its package dependencies:
Once the package is successfully installed, EdSurvey can be loaded with the following command:
The key functions of EdSurvey Version 2.6.9 include:
- data processing, including downloading publicly available data and reading data in R;
- data manipulation, such as the subsetting and merging of data, as well as renaming and recoding variables;
- data exploration, including methods to better understand survey attributes and search for variables and levels in codebooks;
- summary statistics, including unweighted and weighted totals, conditional means, and the percentage of respondents in a category (conditional on an ancillary categorical variable or on the interactions of an arbitrary number of categorical variables), estimation of scale score means based on plausible values;
- percentile that calculates the percentiles of a numeric variable or plausible values;
- analysis of achievement levels and benchmarks for NAEP and international assessment data;
- correlations, including Pearson, Spearman, polyserial, polychoric, and correlation between plausible values, with or without weights applied;
- linear regression with or without plausible values as the dependent variable;
- logistic regression that allows either a discrete variable or dichotomized plausible values as the dependent variable;
- gap analysis that compares the average, percentile, achievement level, or percentage of survey responses between two groups that potentially share members;
- multilevel models that use weights at multiple levels and allowing plausible values in the dependent variable;
- multivariate regression that extends multiple linear regression to include models with multiple outcome variables; and
- quantile regression that fits a quantile regression model that uses weights and variance estimates appropriate for the data.
As the development of EdSurvey progresses, several additional functions, such as direct estimation, IRT, and other statistical methods will be added to the package.
