In markheckmann/OpenRepGrid: Tools to Analyze Repertory Grid Data

library(knitr)
knitr::opts_chunk$set(collapse = TRUE, comment = "#")
options(width=120)
library(OpenRepGrid)

Sometimes basic descriptive measures for constructs and elements, e.g. mean, standard deviation, are neeeded. To prompt descriptive statistics for the constructs and elements of a grid use the function statsConstructs and statsElements. The following measures are returned:

• item name
• item number
• number of valid cases
• mean
• standard deviation
• trimmed mean (with trim defaulting to .1)
• median (standard or interpolated)
• mad: median absolute deviation (from the median)
• minimum
• maximum
• skew
• kurtosis
• standard error

R-Code

The following examples are identical for statsElements. Just replace statsConstructs by statsElements in order to analyze elements.

d <- statsConstructs(fbb2003)
d

The returned object is a dataframe, so you may access them as usual. E.g. to retrieve the means of the constructs, type

d$mean

statsConstructs(fbb2003, trim = 10)

statsConstructs(fbb2003, index=F)
