cat.feedback.irt: Feedback on IRT score

In pmcharrison/psychTestCAT: Computerised Adaptive Testing With PsychTestR

Description

Displays the participant's IRT score and associated standard error to the participant. Most participants won't know what these scores mean; however, this feedback option can be useful to experimenters conducting in-lab studies, because it means they can write down the final scores manually.

Usage

cat.feedback.irt(
  text = "feedback_irt",
  dict = psychTestRCAT::ptrcat_dict,
  next_button = NULL,
  digits_irt_score = 3L,
  digits_irt_sem = 3L
)

Arguments

text	(Character scalar) Text to display to the participant. This text will be treated as an internationalisation key for the dictionary contained in the dict argument; if the key is not present in the dictionary, the text will be displayed as is.
dict	Internationalisation dictionary (see i18n_dict).
next_button	(NULL or a character scalar or an object of class "shiny.tag") If NULL, no next button is shown (typically because the test has completed). Otherwise, a button to progress to the next page is created, displaying the content of this argument.
digits_irt_score	(Numeric scalar) Number of digits to which the IRT score should be rounded.
digits_irt_sem	(Numeric scalar) Number of digits to which the IRT standard error should be rounded.

Value

A timeline segment suitable for inclusion in a psychTestR timeline directly after adapt_test.
