Analysis of Variance Use the graph attached below. In this assignment we are interpreting statistics. Questions for each graph: 1.) ANOVA: Is the overall test significant? 2.)Multiple Comparisons: To know which group are different from another, we need to examine the results from the post hoc test analysis? 3.)Discriptives: Discuss final results using APA format. In addition to referring to information from the previous two tables, you will need to incorporate information from the third table
In Exercises 5–16, use analysis of variance for the indicated test. Lead and Verbal IQ Scores Example 1 used measured performance IQ scores for three different blood lead levels. If we use the same three categories of blood lead levels with measured verbal IQ scores, we get the accompanying Minitab display. (The data are listed in Data Set 7 “IQ and Lead” in Appendix B.) Using a 0.05 significance level, test the claim that the three categories of blood lead level have the same mean verbal IQ score. Does exposure to lead appear to have an effect on verbal IQ scores? Minitab
The normal distribution plays an important role in statistics. Write a briefdescription on each of the following aspects: i) the key features of a normaldistribution; ii) two variables which occur naturally as a normal distribution; iii) a variable where you would prefer to use the median as the measure of centraltendency.
In Exercises 5–16, use analysis of variance for the indicated test. Lead and Full IQ Scores Example 1 used measured performance IQ scores for three different blood lead levels. If we use the same three categories of blood lead levels with the full IQ scores, we get the accompanying Excel display. (The data are listed in Data Set 7 “IQ and Lead” in Appendix B.)

A researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students made toward completing a bachelor's degree. One aspect of his research was to determine whether students who first attended community college took longer to attain a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the results of his study. Complete parts a) through e) below. Click here to view the sample data. Click here to view Student's t-distribution table. D.
