Autism is a disorder that consist of a group of developmental disabilities which can cause children social, behavioral, and communication challenges in children. The article "Cognitive Effects of Risperidone in Children with Autism and Irritable Behavior," that shows the outcome of the research that was done showing the results on the effects of risperidone has on children with autism. In this paper I tend to discuss the questions that the authors are trying to answer, hypothesis that is being tested and the concepts that were applied, assumptions and limitations of the statistical study, how statistical testing was applied and the findings.
Analysis of variance is considered to be a technique that it is often used when comparing a group of means. This statistical technique that is used to analyze variability in data in order to infer the inequality among population means. ANOVA is well known for being a power and flexible statistical tool that can used in complex research. The question that the author was trying to answer was are there any effects of risperidone on the cognitive process in children that suffer from autism and irritable behavior. The null hypothesis would be that risperidone has no effect on cognitive the procedures that affect children with autism and irritable behavior. Thus the alternative hypothesis consist of that risperidone does have an effects on cognitive procedures which in hand can affect children with autism and irritable behavior.
The subjects in the research consisted of thirty-eight children that ranged in the ages of five to seventeen years old. The children who had autism and austere behavior disorder were randomly picked .At random they were given risperidone in the quantities of 0.5 to 3.5 mg/day and there were the others that were on placebo for eight
