Question

Problem #8 Calculate category statistics: Autism is a disability that is characterized by a severely decreased ability to engage in communication and social interaction. A study was undertaken to establish the prevalence of Autism in a community. Data from this stuay are reported below Children Diagnosed With Autism per Age Group Age Group 3-5 6-10 Children With Autism 193,479 175,417 a. Calculate the prevalence rate of autism for the two age categories. b. Calculate the prevalence to a rate per 1,000

Explanation / Answer

Solution:
Total children = 193479 + 175417 = 368896

Prevalence rate = number of people affected at a specified time / total population at that time.

a) For age group 3-5: Prevalence rate = 193479/368896 = 0.525

For age group 6-10: Prevalence rate = 175417/368896 = 0.475

b) prevalence to a rate per 1,000 = Prevalence rate x 1000

prevalence to a rate per 1,000 for age group 3-5 = 0.525 x 1000 = 525

prevalence to a rate per 1,000 for age group 6-10 = 0.475 x 1000 = 475
