Understanding Probability in Children
To make medical decisions involving pros and cons, one also has to understand probability and percentages. This is a preliminary study to evaluate the ability of children to understand probability and percentages.
|Study Design:||Time Perspective: Prospective|
|Official Title:||Evaluation of the Understanding of Probability in Children|
- To compare the percentage of children who answer correctly to a set of mathematical questions to verify the ability of children to understand probability and percentages. The results will be compared to those obtained in children nationwide in 2003. [ Time Frame: During pre-operative visit. ] [ Designated as safety issue: No ]
- The secondary objective is to compare the responses between children and parent. [ Time Frame: During the pre-operative visit. ] [ Designated as safety issue: No ]
|Study Start Date:||August 2007|
|Study Completion Date:||February 2009|
|Primary Completion Date:||February 2009 (Final data collection date for primary outcome measure)|
children between 11 and 13 years of age
children between 14 to 15 years of age
children between 16 and 18 years of age
The concept of patients making decisions with respect to their health care is well accepted in adult medicine but, the value and importance of decision making in the care of children is not recognized. The major objection raised against allowing children to express their opinions concerning outcomes is that children do not understand probability.
One way of assessing children's ability to understand probability is to test their mathematical knowledge using tests focused on probability and percentage.
We have designed a set of questionnaires with 10 questions each, taken from the US Department of Education's National Assessment of Educational Progress (NAEP). They are divided into 3 different groups (4th, 8th, and 12th grade), based on grade-level. We have also obtained the average percentage of correct-incorrect answers given to these questions by students nationwide, and the scoring system used to assess the student's proficiency level.
In this preliminary study we intend to present this set of 10 mathematical questions to children and to one of their parents.
