Final answer:
More boys than girls might be in the Tourette's support group because of the higher diagnosis rates in boys, potentially due to more noticeable symptoms and medical consultation.
Step-by-step explanation:
The reason there were more boys than girls in the Tourette's support group at the hospital might be attributed to the differing rates of diagnosis between genders. This pattern reflects a broader trend in healthcare, where male behavior is often more readily recognized and diagnosed when it aligns with the common symptoms of a condition. In the case of Tourette's syndrome, boys are approximately three to four times more likely than girls to be diagnosed. This disparity could be influenced by various factors including the manifestation of symptoms and the tendency for boys to have more overt or disruptive symptoms that lead to medical attention.
