Description Usage Arguments Value See Also Examples

timss.ben.pv calculates the percentage of students performing at or above the cut-off points (scores) given by the useR. The default are the benchmarks established by PIRLS/TIMSS

1 2	timss.ben.pv(pvlabel, by, cutoff, data, export = FALSE, name = "output", folder = getwd())

`pvlabel`	The label corresponding to the achievement variable, for example, "BSMMAT", for overall math performance.
`cutoff`	The cut-off points for the assessment benchmarks (e.g., cutoff = c(400, 475, 550, 625)).
`by`	The label for the grouping variable, usually the countries (i.e., by="IDCNTRYL"), but could be any other categorical variable.
`data`	An R object, normally a data frame, containing the data from TIMSS.
`export`	A logical value. If TRUE, the output is exported to a file in comma-separated value format (.csv) that can be opened from LibreOffice or Excel.
`name`	The name of the exported file.
`folder`	The folder where the exported file is located.

timss.ben.pv returns a data frame with the percentage of students at or above the benchmark and the corresponding standard error.

The total weight, "TOTWGT" and the cut-off points or benchmarks are defined in the config object.
