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 2.3.2 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)
- 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 Study (ECLS)
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
Unless you already have R version 3.4.0 or later, install the latest R version. Users also may want to install RStudio desktop, which has an interface that many find easier to follow. RStudio is available online from rstudio.
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 2.3.2 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; and
- gap analysis that compares the average, percentile, achievement level, or percentage of survey responses between two groups that potentially share members.
- multilevel models using 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;
- 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.
Data Set Specific Overviews
Documents that describe the analysis of specific survey data in the EdSurvey package include the following:
- Using EdSurvey to Analyze NCES Data: An Illustration of Analyzing NAEP Primer (PDF) describes the basics of using the EdSurvey package for analysis of NAEP data. This vignette covers an introduction to the EdSurvey package with topics such as preparing the R environment for processing, creating summary tables, calculating percentiles and achievement levels, running correlations, linear regression and logistic regression, and conducting gap analysis.
- Using EdSurvey to Analyze TIMSS Data (PDF) describes the methods used in analysis of large-scale educational assessment programs such as Trends in International Mathematics and Science Study (TIMSS) using the EdSurvey package. The vignette covers topics such as preparing the R environment for processing, creating summary tables, running linear regression models, and correlating variables.
- Using EdSurvey to Analyze NAEP Data With and Without Accommodations (PDF) provides an overview of the use of NAEP data with accommodations and describes methods used to analyze this data.
