2. Prepare the solution to the selected exercise showing the solution on a step-by-step basis. If your response is a descriiption of a process, concept, or problem-solving technique then be sure to show at least one example to support your post.
3. Check the solution if possible.
4. Discuss the method of solving the exercise that was used and possible real-world applications that could be solved with the same technique.NEED TO USE THE REFERENCE PROVIDED IN ATTACHMENT PLEASE.

A Social Identity Perspective of Social Media’s Impact on Satisfaction With Life

I am doing a research paper and this class is Intro to Statistical Analysis. My topic I am researching and doing a paper on is.
Topic: A Social Identity Perspective of Social Media’s Impact on Satisfaction with Life
I will include the instructions and also the rubric and if it is good, I would like to use the same writer for this course as this paper builds from week to week. The paper needs to use my topic. Thank you

Magic Squares

Assignment 2
Magic Squares
Magic square puzzles have intrigued people for hundreds of years. A magic square puzzle is an arrangement of numbers in the shape of a square. The number of rows and columns are required to be identical, and the sum of each vertical column, horizontal row, and diagonal to be equal. The Chinese were given credit for creating the magic square. Today, magic square puzzles can be seen in math tournaments and other venues for recreational mathematics. Research the origin of the magic squares and their mathematical applications and then create an original magic square. Provide a detailed descriiption of how to solve the puzzle and provide at least two solutions for your square. Indicate how you will use this activity with your students.

Hello ,
You will follow through questions asked in Domain 1 , 2, and 3 in the word document. Answer should be submitted and returned using the document. this is a reflection on a teaching lesson you have taught . the lesson you have thought it about difference of two square . I wrote a quick summary of the lesson. even though you personally did not teach it . you will have to pretend you did using the video , summary and lesson plan provide to write the reflection on all 3 part I have a uploaded a guide you can use for another lesson. I am expecting a total of up 350 words for each for each section domain 1, 2, and 3 . Do not complete section 4.
Please remember no source or quote should be use . you should return a response that look like the sample template of from the Hand washing template . but use topic on the difference of two square

Choose a research question you want i do not mind what it is.
This week’s main Discussion requires you to answer the question completely and correctly to receive full credit.
This week we talk about the uses of a crosstabulation (crosstabs) and the benefits of creating this “snapshot” of your data.
For this forum, provide a brief introduction to your study to remind your classmates what we are reading about here. Include:
1. Your overall research question
2. The research hypothesis and null hypothesis
Next, create a crosstab for your data and include it in the post. Be sure to explain your findings, including a description of the data, a calculation of the epsilons, and a discussion of the 10% rule. The epsilons in short are the differences between the highest and lowest column % in any given row. As long as one epsilon makes the 10% threshold, we’ll deem two variables have “enough” going on to with each other to warrant further statistical analysis.
Special note:
When a variable is continuous (interval/ratio level of measurement), for example, age of respondent, we do not run crosstabs directly b/c it will result in a really spread-out table with lot of 0s and low frequency cells. Such a crosstab does not help us understand the data.
The correct way is to reduce the level of measurement to either ordinal level or nominal level (group the numbers into categories) and then run the cross table. You do this by recoding (as you demonstrated in Assignment 1). In this way, your crosstabs will help us better understand data. Here is another example of recoding in a video.
Discussion Guidelines
Week 4 Forum Crosstabs.pdf
You must start a thread before you can read and reply to other threads
Week 4 wrap up
Class-
As we wrap up week 4, please be reminded of:
1. wording research questions and hypotheses for crosstabs (correlation or relationship)
2. data assumptions of either nominal or ordinal data for crosstabs
3. recoding continuous data into categories
4. interpretation of epsilons and the 10% rule to assess crosstab relationships between variables

Purpose This assignment provides an opportunity to develop, evaluate, and apply

Purpose This assignment provides an opportunity to develop, evaluate, and apply bivariate and multivariate linear regression models. Resources: Microsoft Excel®, DAT565_v3_Wk5_Data_File Instructions: The Excel file for this assignment contains a database with information about the tax assessment value assigned to medical office buildings in a city. The following is a list of the variables in the database: FloorArea: square feet of floor space Offices: number of offices in the building Entrances: number of customer entrances Age: age of the building (years) AssessedValue: tax assessment value (thousands of dollars) Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics. Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of FloorArea and AssessmentValue. Is FloorArea a significant predictor of AssessmentValue? Construct a scatter plot in Excel with Age as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of Age and Assessment Value. Is Age a significant predictor of AssessmentValue? Construct a multiple regression model. Use Excel’s Analysis ToolPak to conduct a regression analysis with AssessmentValue as the dependent variable and FloorArea, Offices, Entrances, and Age as independent variables. What is the overall fit r^2? What is the adjusted r^2? Which predictors are considered significant if we work with α=0.05? Which predictors can be eliminated? What is the final model if we only use FloorArea and Offices as predictors? Suppose our final model is: AssessedValue = 115.9 + 0.26 x FloorArea + 78.34 x Offices What wouldbe the assessed value of a medical office building with a floor area of 3500 sq. ft., 2 offices, that was built 15 years ago? Is this assessed value consistent with what appears in the database?
