Detailed Description

The leafs of the analysis data structure.

• There is a separate data structure for each question or sub question's analysis core_question::statistics::responses::analysis_for_question or core_question::statistics::responses::analysis_for_question_all_tries.
• There are separate analysis for each variant in this top level instance.
• Then there are class instances representing the analysis of each of the sub parts of each variant of the question. core_question::statistics::responses::analysis_for_subpart.
• Then within the sub part analysis there are response class analysis core_question::statistics::responses::analysis_for_class.
• Then within each class analysis there are analysis for each actual response core_question::statistics::responses::analysis_for_actual_response.

string	$whichtries	which tries have been analysed?
int	$questionid	which question.
int	$variantno	which variant.
string	$subpartid	which sub part is this actual response in?
string	$responseclassid	which response class is this actual response in?
int | null	$calculationtime	time when the analysis was done. (Defaults to time()).

data_for_question_response_table()

core_question\statistics\responses\analysis_for_actual_response::data_for_question_response_table	(		$partid,

(

$try = 0

)

Used to count the occurrences of response sub parts.

Parameters
