This assignment provides an opportunity to develop, evaluate, and apply bivariate and multivariate linear regression models.

Resources: http://myresource.phoenix.edu/secure/resource//DAT565v3/DAT565_v3_Wk5_Data_File.xlsx
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?

Contrasts Between Conventional and Alternative Medicine

AlternativeDoctorThe progress of science is generally accepted to have improved the nature of numerous procedures, items, and administrations. Be that as it may, in specific circles of life, customary strategies are as yet being utilized; medication is a splendid case of the concurrence of two antipodal methodologies. Alongside ordinarily perceived regular medication dependent on science and innovation, there likewise exists elective medication, which once in a while incorporates rehearses created a large number of years back. The predominance of every one of these sorts of medication have a long-standing history, as every one of them have demonstrated its adequacy; thusly, understanding their favorable circumstances and downsides is urgent for framing one’s own perspective.

The main contrast between these two frameworks is their way to deal with analysis. Traditional medication centers around the components that cause sicknesses and helping their manifestations; each variation from the norm is viewed as a free proviso, separate from the character of an individual and their condition. In contrast to its partner, elective medication considers a to be as a harmony of interrelations between a body and its condition; in this way, an ailment is believed to be brought about by a lopsidedness between them. At the end of the day, elective medication centers preferably around purging the whole framework over on restoring its specific components (Buzzle).
