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.
