SPHS 500 APU Statistics Effect Size Power Correlation Discussion
Part 1:
provide an example of two variables that are correlated in a strong and positive direction and two that are correlated in a strong a negative direction. You aren't required to provide a research article to support these relationships but you are welcome to if you chose. Please comment on any other factors that could influence their relationship and what can an cannot be inferred from these correlations. Topics are first-come, first-serve so please select examples that no other classmates have chosen.
Part 2: I need the answers for the questions attach to this post.

MEDIATION REGRESSION MODEL SPSS, APA format
Moderator Problem (Background):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 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.Describe the sample, the goals of the study, and the variables employed to conduct the studyDescribe the analysis strategy – How will you analyze the data.State the Null and Alternative HypothesesConduct 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).Present and summarize the results for the Multiple Regression Analysis – including the effects for both IVs as well as the interaction.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 analysis in which the variable Grades is the DV (outcome) and Absences is the IV (predictor).Create the appropriate table of results for the multiple regression analysis (you must refer to this table within the summary).Create the appropriate table for the simple slopes analyses.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.In the Week 2 forum you must 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.Please carefully read my sample summary and model your summary after it. Also, you must read chapter 15 in the Warner text.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 assignment3 hours agoATTACHMENTS

Linear Optimization - Part 1 is attached. Linear Optimization - Part 2The purpose of this assignment is to solve business problems using linear optimization techniques and interpret the results to determine optimal solutions for business problems.Using specified data files, chapter example files, and templates from the “Topic 5 Student Data, Template, and Example Files” topic material, complete Chapter 14, Problems 79 (part a), 80 (part a), 81, 86 (part a), and 89 from the textbook. Use Microsoft Excel’s Solver Add-In to complete these problems. For all problems except 89, run the Solver’s Answer and Sensitivity Reports. Interpret and summarize the key results.To receive full credit on the assignment, complete the following.Ensure that all Solver settings are defined through the use of the Solver dialog box.Ensure that Excel files include the associated cell functions and/or formulas if functions and/or formulas are used.Include a written response to all narrative questions presented in the problem by placing it in the associated Excel file.Include Answer and Sensitivity Reports interpretation and summary of key results.Place each problem in its own Excel file.

SOLUTION: descriptive statistics, statistics homework.
Doug and David are researchers who examine youth health. Numerous recent studies have
suggested that youth in the 10-15 year old range are increasingly engaged in many hours of
video game playing, they are not active enough (as defined by at least one hour of exercise
per day), and they are disconnected to their family units. However, in some of their own
previous research Doug and David found that although students play a lot of video games
they remain active and engage in sufficient exercise. In their current study they asked
children to keep a log and then to report for a given week the number of hours of video game
playing and exercise that they engage in and also to report the number of dinners that their
families eat together as a measure of family connection. They also collected gender and age
as demographic data. (data chart attached as Jpeg) 1. What are the measures of central tendency for female participants for playing video
games and exercising? 2. What are the variance and standard deviation for female participants for playing video
games and exercising? 3. What are the measures of central tendency for male participants for playing video games
and exercising? 4. What are the variance and standard deviation for male participants for playing video
games and exercising? 5. Develop a frequency polygon that compares male and female participants for playing
video games and exercising. (This can be done using Excel or hand drawn take a picture
and insert) 6. Summarize the findings comparing female to male habits of playing video games and
exercising.
