cat.feedback.iq: Feedback on IQ score
In pmcharrison/psychTestCAT: Computerised Adaptive Testing With PsychTestR

Provides feedback for the adaptive test framed in terms of an 'IQ' score. IQ scores are rescaling of IRT scores to a scale with mean 100 and standard deviation 15. The feedback also provides an interpration of the IQ score as a percentile with respect to the general population.

cat.feedback.iq(
  test_label,
  text = "feedback_iq",
  dict = psychTestRCAT::ptrcat_dict,
  next_button = NULL,
  digits_iq = 0L,
  digits_percentile = 0L
)

`test_label`	(Character scalar) The label for the test, e.g. "MDT". This will be used to label the IQ score, e.g. "Your MDT-IQ was...".
`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_iq`	(Numeric scalar) Number of digits to which the IQ score should be rounded.
`digits_percentile`	(Numeric scalar) Number of digits to which the percentile score should be rounded.
`feedback_iq`	(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.
