26-24 ژوئن 2019- کپنهاگ دانمارک  

هشتمین کنفرانس تحقیقات بین المللی IEA (IRC-2019) کارگاه هایی در زمینه تحلیل داده­های ثانویه در تاریخ های 2 تا 4 تیر ماه 1398 برگزار می کند که یکی از آن­ها آموزش بسته EdSurvey در محیط R است. این بسته توسط NCES تدوین شده است.

موضوعات این کارگاه عبارتند از:

• R basics, including getting to know the R environment and R language, and package installation;
• Data processing, including downloading publicly available data and reading data in R;
• Data manipulation, including subsetting and merging data, and renaming and recoding variables;
• Cross-tabulation, 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), and estimation of scale score means based on plausible values;
• Calculating the percentiles of a numeric variable or plausible values;
• Analysis of benchmarks for 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, comparing the average, percentile, achievement level, or percentage of survey responses between two groups that potentially share members.
