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)
Arguments
x |

index |
Whether to print the number of the element. |
trim |
The number of characters an element or a construct
is trimmed to (default is

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
Note
Note that standard deviation and variance are estimations,
i.e. including Bessel's correction. For more info type ?describe
