If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI? Alternatively, find an article that uses regression analysis to study a medical concern. In that study, what was the dependent variable, and what was the independent variable(s)? Further, how would you use this study to highlight the difference between correlations and causation?

A Psychology Professor is interested in understanding the variability in final exam grades for his 100-level freshman Psychology Statistics class.  He hypothesizes that class absences would be negatively correlated with final exam grades and that the students’ pre-college levels of math proficiency would be positively correlated with final exam grades. He also hypothesizes that the relationship between absences and final grades would be moderated by levels of Math proficiency.  The professor collects data for 35 students. Based on Placement Test Scores, obtained during pre-semester orientation/registration, 12 students had low (Developmental level) Math skills.  Thirteen students were proficient in basic 9th-grade Arithmetic and Algebra only. And, 10 students had advanced Math skills at the Calculus level.  Math levels were recorded as 1 = Low Math Skills; 2 = Moderate Skills, and 3 = High math skills.  At the end of the semester, and for each student, the number of class absences was recorded, as were their final exam grades. Using the data appearing in the attached Week 3 Moderator “Statistics Grades.sav” SPSS data file, conduct a multiple regression analysis to examine the direct and interactive (moderator) effects of absences and Math level on final exam grades.  Summarize the results using the correct APA style. Be sure to include the appropriate Tables and Graphs. Please use my sample summary for moderation as a guide for your summary. As you’ll see, my sample summary shows you what statistics to present and summarize in your papers, and how to present them in APA style format. Assignment Requirements. 1-Describe the sample, the goals of the study, and the variables employed to conduct the study 2-Describe the analysis strategy – How will you analyze the data. 3-State the Null and Alternative Hypotheses 4-Conduct the multiple regression analysis in which grades is the DV (outcome), Math Levels, and Absences, as well as their centered interaction, are the IV (predictors). 5-Present and summarize the results for the Multiple Regression Analysis – including the effects for both IVs as well as the interaction. 6-Conduct, present, and summarize the results for the simple slopes analyses for each level of Math proficiency.  So, using the split file procedure in SPSS you must conduct 3 simple regression analyses in which the variable Grades is the DV (outcome) and Absences is the IV (predictor). 7-Create the appropriate table of results for the multiple regression analysis (you must refer to this table within the summary). 8-Create the appropriate table for the simple slopes analyses. 9-Create a simple slopes plot showing the regression of grades on absences for each Math level. You must refer to this figure within the summary. 10-Submit the summary as an MS-Word file, and please submit the SPSS output in a separate file.  That way I can see the analyses that you ran. 11-Please carefully read my sample summary  and model your summary after it.  Also, you must read chapter 15 in the Warner text. 12-Please note that this analysis and summary must be your own original work, you may not share you work with any classmates.  I created the practice data and sample summary as an in-class problem, and I encourage you with work together on the practice problem. But not on the graded assignment  For more information on Arithmetic and Algebra read this: https://en.wikipedia.org/wiki/Arithmetic

Scaffolding of concepts in math instruction is imperative for students to master concepts and develop strong mathematical literacy. Math is a subject that naturally continues to deepen students’ comprehension of concepts as they progress through the grade levels. For example, during primary grade instruction, students learn basic addition concepts. In later grades, addition comprehension develops into repeated addition that in turn leads into an understanding of multiplication and so on. Building a strong mathematical foundation in early education using various learning strategies in units of study ensures that the teacher is meeting the needs of all learners. For this assignment, select a grade level K-3 and at least one state standards related to mathematical operations. Using the “COE Lesson Plan Template,” develop a lesson based on your selected standards. As you are developing your lesson, consider how to create objectives that measure students’ actions and incorporate differentiated learning to meet the needs of students at, above, and below grade level. For this assignment, you do not need to complete the “Multiple Means of Expression” section in the “COE Lesson Plan Template.” As you develop your lesson, consider how this lesson would scaffold with other lessons. Below your lesson plan, write a 150-250 word reflection describing the following: What knowledge and skills would need to be taught before this lesson to make sure students are able to retain the content? What lessons would logically be taught after this lesson to take students to the next level of understanding? How would you differentiate to meet the needs of students above and below grade level? APA format is not required, but solid academic writing is expected. readings- https://lopes.idm.oclc.org/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=ehh&AN=116991181&site=ehost-live&scope=site https://lopes.idm.oclc.org/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=ehh&AN=123323488&site=ehost-live&scope=site https://lopes.idm.oclc.org/login?url=http://search.ebscohost.com/login.aspx?direct=true&db=ehh&AN=123903475&site=ehost-live&scope=site https://www.verywellfamily.com/universal-design-learning-4141046 https://dreme.stanford.edu/news/math-games-excite-young-minds  http://thinkmath.edc.org/resource/kindergarten  For more information on Mathematical Foundation read this: https://en.wikipedia.org/wiki/Mathematics?wprov=srpw1_0

Suppose that there are two candidates in the upcoming presidential election, candidate A and candidate B. Sara note that she has discussed the presidential election candidates with 15 friends, and 10 said that they are voting for candidate A. Sara is therefore convinced that candidate A will win the election because A gets more than 50 percent of votes. Answer the following questions in a Word document and submit: Based on what you now know about statistical inference, is Sara’s conclusion a logical conclusion? Why or why not? How many friend samples Sara should have in order to draw the conclusion with a 95 percent confidence interval? Why? How would you explain your conclusion to Sara without using any statistical jargon? Why? For more information on Statistical Inference read this: https://en.wikipedia.org/wiki/Statistical_inference

It is important for all students, especially students with disabilities, to be exposed to content-based lessons that promote critical thinking and problem-solving. There are many areas that a student may struggle in when it comes to mastering complex mathematical tasks. For this reason, it is imperative that teachers are equipped with various instructional strategies for handling these situations. Part 1: Operation and Algebraic Thinking Lesson Plan Using the “COE Lesson Plan Template,” design a lesson for the 1-5 grade level of your choice and a corresponding Arizona or other state math standard within the Operation and Algebraic Thinking domain. Locate four lesson plans that focus on your chosen grade level and math standard from four different websites to review. Using the lesson plans as resources, design a new operation, and algebraic thinking lesson plan that encourages critical thinking. The lesson plan must include differentiated strategies for students who struggle with perception and attention as well as differentiation strategies for students who struggle with memory and retrieval. Part 2: Instructional Strategies Rationale In 250-500 words, reflect upon your instructional choices and rationalize the appropriateness of each strategy related to the specified student needs and learning target. Describe how each strategy encourages critical thinking specific to your lesson. Support your choices with this topic’s readings and a minimum of two scholarly resources. In addition, cite the websites you used as references to develop your lesson plan. While APA format is not required for the body of this assignment, solid academic writing is expected, and in-text citations and references should be presented using APA documentation guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

During the recent election season, you saw many instances where polls were taken and reported, along with the confidence level of the estimate. For example, a poll showed that one candidate had a “”voting for” level of 37%+/-4. The opposing candidate had a score of 39%+/-4 at a 95% confidence level. Because the poll is not a census sample, a sample may be “good” but will have variation around the TRUE population proportion or mean. Thus, the poll is an estimate. The +/- value establishes a range within which the true population proportion is said to be, give a certain level of confidence. However, the reporter said that the second candidate had “a slight lead”. Is this a true statement? Why could it be argued that the scores are “statistically the same”?
