(Incidence is one of these.) Carefully read Scenario 1 below and answer questions 11-14 which follow.Scenario 1: A team of Epidemic Intelligence Service officers from the CDC arrives in Rhode Island to assist the state health department with investigation and control of an outbreak of measles.The team is asked to include the entire state in the investigation; thus, a confirmed case of measles in this outbreak is any resident of Rhode Island with an illness clinically compatible with measles who either has a positive laboratory test for measles or is a contact of someone with a positive test.Individuals with clinically compatible illnesses who did not have laboratory confirmation and were not contacts were classified as “possible cases”.(No recovery date would mean that the individual is still sick, or did not recover during the time frame of interest. No lab or contact is a non-confirmed case and these are considered the "possible cases". These cases are not included depending on the question being asked, specifically prevalence & incidence, because they are not confirmed with the illness.) The team members arrive in Rhode Island on March 1st and spent a month investigating.They found case information as detailed in the chart below.

week7assignment
You had the chance earlier in the week to practice with the one-way ANOVA and obtain peer feedback. Now it is time to put all of that good practice to use and answer a social research question with the one-way ANOVA. As you head into the assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure the dependent and independent variables (factor) are amenable to use in the ANOVA (i.e., be sure to note levels of measurement).For this Assignment, you will examine the one-way ANOVA based on a research question.To prepare for this Assignment:Review this week’s Learning Resources and media program related to one-way ANOVA testing.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a one-way ANOVA.Once you perform your one-way ANOVA analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2- to 3-paragraph analysis of your one-way ANOVA results for your research question. Include any post-hoc tests with an analysis of the strength of any relationship found (effect size). Also, in your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

underdevelopment of social cognition,, statistics homework help
Question: Suppose you are interested in how children with severe autism experienced the receipt of special education assistance in public schools. This population is characterized by underdevelopment of social cognition, social skills, and language skills. What is the best method for collecting data to answer your research question? Why is this method best? How would you describe the research design?My response to question: Based on the fact that the children have severe autism, I would utilize is a qualitative methodology with a case study design. Case studies, in their true essence, explore and investigate contemporary real-life phenomenon through detailed contextual analysis of a limited number of events or conditions, and their relationships, and in this case, the severe autism (Yin & Moore, 1987). My method of sampling would be convenience and I would use questionnaires, and ask open-ended questions (Cresswell, 2009). Case study method has sometimes been criticized for its lack of rigor and the tendency for a researcher to have a biased interpretation of the data (Stake, 1995). Grounds for establishing reliability and generality are also subjected to skepticism when a small sampling is deployed. Often time, case study research is dismissed as useful only as an exploratory tool. Despite these criticisms, researchers continue to deploy the case study method particularly in studies of real-life situations governing social issues and problems, and in this case, the severe autism.Professor's question that I request answer to: Thank you Janet! Your recommendations on the use of a case study design are valid and do align to the characteristics of this study. You mention using questionnaires and asking open ended questions but who will answer these questions? Also, one of the requirements of a case study design is using at least three forms of data in order to triangulate (and validate) the results obtained. Which other methods would you consider in order to build a sound study that evaluates the "receipt" of special education students by these autistic children in public schools? Any ideas/suggestions?

You had the chance earlier in the week to practice with the one-way ANOVA and obtain peer feedback. Now it is time to put all of that good practice to use and answer a social research question with the one-way ANOVA. As you head into the assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure the dependent and independent variables (factor) are amenable to use in the ANOVA (i.e., be sure to note levels of measurement).For this Assignment, you will examine the one-way ANOVA based on a research question.To prepare for this Assignment:Review this week’s Learning Resources and media program related to one-way ANOVA testing.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a one-way ANOVA.Once you perform your one-way ANOVA analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2- to 3-paragraph analysis of your one-way ANOVA results for your research question. Include any post-hoc tests with an analysis of the strength of any relationship found (effect size). Also, in your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

underdevelopment of social cognition,, statistics homework help
Question: Suppose you are interested in how children with severe autism experienced the receipt of special education assistance in public schools. This population is characterized by underdevelopment of social cognition, social skills, and language skills. What is the best method for collecting data to answer your research question? Why is this method best? How would you describe the research design?My response to question: Based on the fact that the children have severe autism, I would utilize is a qualitative methodology with a case study design. Case studies, in their true essence, explore and investigate contemporary real-life phenomenon through detailed contextual analysis of a limited number of events or conditions, and their relationships, and in this case, the severe autism (Yin & Moore, 1987). My method of sampling would be convenience and I would use questionnaires, and ask open-ended questions (Cresswell, 2009). Case study method has sometimes been criticized for its lack of rigor and the tendency for a researcher to have a biased interpretation of the data (Stake, 1995). Grounds for establishing reliability and generality are also subjected to skepticism when a small sampling is deployed. Often time, case study research is dismissed as useful only as an exploratory tool. Despite these criticisms, researchers continue to deploy the case study method particularly in studies of real-life situations governing social issues and problems, and in this case, the severe autism.Professor's question that I request answer to: Thank you Janet! Your recommendations on the use of a case study design are valid and do align to the characteristics of this study. You mention using questionnaires and asking open ended questions but who will answer these questions? Also, one of the requirements of a case study design is using at least three forms of data in order to triangulate (and validate) the results obtained. Which other methods would you consider in order to build a sound study that evaluates the "receipt" of special education students by these autistic children in public schools? Any ideas/suggestions?
