As the most frequent human chromosomal abnormality (i.e., trisomy of Chromosome 21), Down syndrome occurs in approximately 1.5 per 1,000 live births. A. Generally speaking, what are the reading difficulties of children with Down syndrome? Where can the reading difficulties be traced to? B. List ONE effective reading instructional strategy for children with Down syndrome. C. You aim to compare the effectiveness of this strategy for children with Down syndrome to the effectiveness for children with William syndrome. Design an intervention study to address this research aim. Describe the participants in your overall sample and the sub-sample groups. What are three independent variables (including covariates) you will measure? Why and how will you collect data on those independent variables? What are two dependent variables you will measure? Why and how will you collect data on those dependent variables? Describe the group-level research design you will use, including when you will collect data on each of the variables above, and how your design addresses issues of validity. Write two testable research questions for your study. Your research questions should explicitly address the research aim. Be sure that you have referred to each of the independent and dependent variables somewhere in the research questions. For each research question, describe the statistical analysis you will perform to test the research question. Be clear about how you will include each of your variables as part of the statistical analysis.
