In this project you will be using the Stat_Grades.savdatafile that is found in Doc Sharing under the Instructor-Graded Projects:Not all questions require the use of the Stat_Grades.savfile.You may insert your answers, including any charts, graphs, or output, on this document.Write your responses using complete sentences and include appropriate references.Be sure to put your name on this document and save it to your computer.1.There are many variables in the Stat_Grades.sav data set that can be used to describe the students in the class. Use the variable â€œYear in Schoolâ€ and answer the following questions:a. What type of data does the variable â€œYear in Schoolâ€ represent? Are the data discrete or continuous? Explain the Level of Measurement used to assign numbers to the â€œYear in School?â€b. Which measure of central tendency is best to use to describe the variable â€œYear in School?â€ What does that measure tell you about the students in the Statistics Class?â€c. Explain which measure of central tendency is LEAST appropriate to describe the variable â€œYear in School?d. Choose an appropriate graph to display the variable â€œYear in School.â€ Create the graph in SPSS, copy the graph and paste it below. Be sure the graph is titled and fully labeled.2. There are many variables in the Stat_Grades data file that can be used to describe the students in the class. Use the variable â€œShort Form IQ Test Scoreâ€ and answer the following questions:a. What type of data does the variable â€œShort Form IQ Test Scoreâ€ represent? Are the data discrete or continuous? Explain the Level of Measurement used to assign numbers to â€œShort Form IQ Test Score?â€b. Which measure of central tendency is the best one to use to describe the variable â€œShort Form IQ Test Score?â€ What does that measure tell you about the students in the Statistics Class?â€c. Which measure of central tendency is LEAST appropriate to describe the variable â€œShort Form IQ Test Score?d. Choose an appropriate graph to display the variable â€œShort Form IQ Test Score.â€ Create the graph in SPSS, copy the graph and paste it below. Be sure the graph is fully labeled.3. Use the variable Total Course Points and the variable Final Grade to describe the performance of the 105 students from the statistics class in the Stat_Grades data file. Be sure to include at minimum: at least oneappropriate graph, and the appropriate measures of central tendency, and any other numerical descriptors you feel would help convey to the reader the performance of the students in the class. Be sure to include a summary statement after conducting your analysis.4.Which one of the five Quizzes has the strongest relationship with overall student performance represented by â€œTotal Course Points?â€ Create the appropriate graph to show the relationship between the Quiz with the strongest relationship and Total Course Points.5. What is the numerical measure of the strength of the relationship between â€œPrevious GPAâ€ and â€œFinal Exam Points?â€ What kind of a relationship exists? Create the appropriate graph to show the relationship between the Previous GPA and â€œTotal Course Points.â€6. The following output was generated for the variable â€œEthnicityâ€ from the Stat_Grades data set.a. Explain what each measure tells you about the Ethnicity of the students in the Stat_Grades.sav dataset.b. If you were running the Frequencies procedure on the variable â€œEthnicityâ€ why or why not would you include each of these measures?7. The graph below (which is not from data in the Stat_Grades data set) shows the relationship between the time off (vacation hours) and GPA for 100 adult students.a. What type of correlation is displayed?b. Which of the following would you estimate to be the correlation?1. -0.752. -0.303. +0.054. +0.258. The graph below is a histogram showing the ethnicity of the students from the Stat_Grades data set. Is this graph the most appropriate graph for these data? If so, why? If not, why not and what graph might you suggest be used?9. In an article on the relationship between parents or extended family members who are addicts and the likelihood a child would become an addict the correlation is claimed to be statistically significant with a reported correlation of r = +1.35. Do you agree with this claim? Why or why not?10. Use the following graph to decide which measure of central tendency would be the most appropriate to represent the data and why it would be the most appropriate.Submitting your ProjectMake sure your name is on your project and saved to your computer.
