The EdSurvey
package is designed to help users analyze data from the National Center for Education Statistics (NCES), including the National Assessment of Educational Progress (NAEP) datasets. Because of their scope and complexity, these datasets require special statistical methods to analyze. The EdSurvey
package gives users functions to perform analyses that account for both complex sample survey designs and the use of plausible values.
The EdSurvey
package also seamlessly takes advantage of the LaF
package to read in data only when it is required for an analysis. Users with computers that have insufficient memory to read in the entire NAEP datasets can still do analyses without having to write special code to read in just the appropriate variables. This is all addressed directly in the EdSurvey
package---behind the scenes and without additional work by the user.
Several vignettes are available to assist in analyzing NCES data:
Using EdSurvey to Analyze NCES Data: An Illustration of Analyzing NAEP Primer is an introduction to the basics of using the EdSurvey
package for analyzing NCES data, using the NAEP Primer as an example. The vignette covers topics such as preparing the R environment for processing, creating summary tables, running linear regression models, and correlating variables.
Exploratory Data Analysis on NCES Data provides examples of conducting exploratory data analysis on NAEP data.
Calculating Adjusted p-Values From EdSurvey Results describes the basics of adjusting p-values to account for multiple comparisons.
Using the getData
Function in EdSurvey describes the use of the EdSurvey
package when extensive data manipulation is required before analysis.
Using EdSurvey to Analyze NAEP Data With and Without Accommodations provides an overview of the use of NAEP data with accommodations and describes methods used to analyze this data.
Using EdSurvey to Analyze TIMSS Data is an introduction to 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 for Trend Analysis describes the methods used in the EdSurvey
package to conduct analyses of statistics that change over time in large-scale educational studies.
Producing \LaTeX \ Tables From edsurveyTable Results With edsurveyTable2pdf details the creation of pdf summary tables from summary results using the edsurveyTable2pdf
function.
Documents that describe the statistical methodology used in the EdSurvey
package include the following:
Statistical Methods Used in EdSurvey details the estimation of the statistics in the lm.sdf
, achievementLevel
, and edsurveyTable
functions.
Analyses Using Achievement Levels Based on Plausible Values describes the methodological approaches for analyses using NAEP achievement levels.
Methods Used for Gap Analysis in EdSurvey covers the methods comparing the gap analysis results of the EdSurvey
package to the NAEP Data Explorer.
Methods Used for Estimating Percentiles in EdSurvey describes the methods used to estimate percentiles.
Methods Used for Estimating Mixed-Effects Models in EdSurvey describes the methods used to estimate mixed-effects models with plausible values and survey weights, and how to fit different types of mixed-effects models using the EdSurvey package.
Methods and Overview of Using EdSurvey for Multivariate Regression details the estimation of multivariate regression models using mvrlm.sdf
.
Methods and Overview of Using EdSurvey for Running Wald Tests describes the use of the Wald test to jointly test regression coefficients estimated using lm.sdf
and glm.sdf
.
Unless you already have R version 3.2.0 or later, install the latest R version---which is available online at https://cran.r-project.org/. Users also may want to install RStudio desktop, which has an interface that many find easier to follow. RStudio is available online at https://www.rstudio.com/products/rstudio/download/.
