Creates questions for the ranking quiz by combining acute (micromort) and chronic (microlife) risks, converting to a common Loss of Life Expectancy (LLE) scale, and grouping into rankable sets.
Usage
ranking_quiz_questions(
tags = NULL,
items_per_question = 3L,
n_questions = 5L,
seed = NULL,
difficulty = NULL
)Arguments
Character vector of tags to include (e.g. "Radiation", "Travel"). Use
NULLfor all tags. Seeranking_tag_mapping()for available tags.- items_per_question
Integer. Number of items per question (2, 3, or 4). Default 3.
- n_questions
Integer. Number of questions to generate. Default 5.
- seed
Optional integer seed for reproducibility.
- difficulty
Optional difficulty level: "easy", "medium", "hard", or "mixed". Easy = large LLE spread within question, hard = small spread.
Value
A tibble with columns:
question_id,tag,item_name,item_source("acute"/"chronic"),lle_minutes,micromorts,microlives_per_day,category,description,help_url,correct_rank,difficulty
