Data Analysis Project You have contracted with a local school district to help them decide whether to use an interactive computer program or a standard chapter from a textbook to teach students to use fractions. The school did a pilot study of the achievement levels where students were randomly assigned to one of the conditions. The school obtained the following results: Computer Mediated Approach Textbook Approach 9'? 58 89 918 95 'i'5 T9 83 93 4? 1. Use summary calculations of the mean, standard deviation, and range for each condition to describe the characteristics of the two samples. What can you tell the school district about these two samples based on your descriptive analyses? Explain in simple terms in complete sentences. 2. The school wants you to tell them if there is a reliable difference in achievement levels between the computerized and standard textbook groups. Briey describe the appropriate statistical strategy that you are going to use to address this problem. Be sure to explain the rationale behind your choice of strategy. For example. how are you going to analyze the data? what level of measurement is the data? What kind of statistical anal sis or method are you going to use to intgpret the data and why? 3. Perform the statistical procedures necessary to develop and document and state your conclusion about the mean diEt'erenoes between the two groups. 4. Graph the mean performance of the two groups. 5. Explain and defend your conclusions in response to the school district's question. What are you going to tell the school district about these two samples based on your analyses? Explain in complete sentences and in terms a person with limited skills and understanding of basic math or statistics could understand
