statsElements: Descriptive statistics for constructs and elements of a grid.

Description

Descriptive statistics for constructs and elements of a grid.

Descriptive statistics for constructs and elements of a grid.

Usage

statsElements(x, index = TRUE, trim = 20)
statsConstructs(x, index = T, trim = 20)

Value

A dataframe containing the following measures is returned invisibly (see describe):

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

Arguments

x

repgrid object.

index

Whether to print the number of the element.

trim

The number of characters an element or a construct is trimmed to (default is 20). If NA no trimming occurs. Trimming simply saves space when displaying correlation of constructs or elements with long names.

Examples

if (FALSE) {

   statsConstructs(fbb2003)
   statsConstructs(fbb2003, trim=10)
   statsConstructs(fbb2003, trim=10, index=F)

   statsElements(fbb2003)
   statsElements(fbb2003, trim=10)
   statsElements(fbb2003, trim=10, index=F)

   # save the access the results
   d <- statsElements(fbb2003)
   d
   d["mean"]
   d[2, "mean"]  # mean rating of 2nd element
 
   d <- statsConstructs(fbb2003)
   d
   d["sd"]
   d[1, "sd"]   # sd of ratings on first construct
}
