Class: quiz_statistics_table - X-Ref
This table has one row for each question in the quiz, with sub-rows whenrandom questions and variants appear.
There are columns for the various item and position statistics.
| __construct() X-Ref |
| Constructor. |
| statistics_setup($quiz, $cmid, $reporturl, $s) X-Ref |
| Set up the columns and headers and other properties of the table and then call flexible_table::setup() method. param: object $quiz the quiz settings param: int $cmid the quiz course_module id param: moodle_url $reporturl the URL to redisplay this report. param: int $s number of attempts included in the statistics. |
| wrap_html_start() X-Ref |
| Open a div tag to wrap statistics table. |
| wrap_html_finish() X-Ref |
| Close a statistics table div. |
| col_number($questionstat) X-Ref |
| The question number. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_icon($questionstat) X-Ref |
| The question type icon. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_actions($questionstat) X-Ref |
| Actions that can be performed on the question by this user (e.g. edit or preview). param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_qtype($questionstat) X-Ref |
| The question type name. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_name($questionstat) X-Ref |
| The question name. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_s($questionstat) X-Ref |
| The number of attempts at this question. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_facility($questionstat) X-Ref |
| The facility index (average fraction). param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |

| The standard deviation of the fractions. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_random_guess_score($questionstat) X-Ref |
| An estimate of the fraction a student would get by guessing randomly. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_intended_weight($questionstat) X-Ref |
| The intended question weight. Maximum mark for the question as a percentage of maximum mark for the quiz.

| col_effective_weight($questionstat) X-Ref |
| The effective question weight. That is, an estimate of the actual influence this question has on the student's overall mark. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_discrimination_index($questionstat) X-Ref |
| Discrimination index. This is the product moment correlation coefficient between the fraction for this question, and the average fraction for the other questions in this quiz. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| col_discriminative_efficiency($questionstat) X-Ref |
| Discrimination efficiency, similar to, but different from, the Discrimination index. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: string contents of this table cell. |
| is_dubious_question($questionstat) X-Ref |
| This method encapsulates the test for wheter a question should be considered dubious. param: \core_question\statistics\questions\calculated $questionstat stats for the question. return: bool is this question possibly not pulling it's weight? |

| Format inputs to represent a range between $min and $max. This function does not check if $min is less than $max or not. If both $min and $max are equal to null, this function returns an empty string. param: string|null $min The minimum value in the range param: string|null $max The maximum value in the range return: string |
| format_percentage(float $number, bool $fraction = true, int $decimals = 2) X-Ref |
| Format a number to a localised percentage with specified decimal points. param: float $number The number being formatted param: bool $fraction An indicator for whether the number is a fraction or is already multiplied by 100 param: int $decimals Sets the number of decimal points return: string |
| format_percentage_range(float $min = null, float $max = null, bool $fraction = true, int $decimals = 2) X-Ref |
| Format $min and $max to localised percentages and form a string that represents a range between them. This function does not check if $min is less than $max or not. If both $min and $max are equal to null, this function returns an empty string. param: float|null $min The minimum value of the range param: float|null $max The maximum value of the range param: bool $fraction An indicator for whether min and max are a fractions or are already multiplied by 100 param: int $decimals Sets the number of decimal points return: string A formatted string that represents a range between $min to $max. |
