Discussion: Multiple Regression This Discussion assists in solidifying your understanding of statistical testing by engaging in some data analysis. This week you will work with a real, secondary dataset to construct a research question, estimate a multiple regression model, and interpret the results. Whether in a scholarly or practitioner setting, good research and data analysis should have the benefit of peer feedback. For this Discussion, you will post your response to the hypothesis test, along with the results. Be sure and remember that the goal is to obtain constructive feedback to improve the research and its interpretation, so please view this as an opportunity to learn from one another. To prepare for this Discussion: Review this week’s Learning Resources and media program related to multiple regression. Create a research question using the General Social Survey that can be answered by multiple regression. Use SPSS to answer the research question. Post your response to the following: What is your research question? What is the null hypothesis for your question? What research design would align with this question? What dependent variable was used and how is it measured? What independent variable is used and how is it measured? What other variables were added to the multiple regression models as controls? What is the justification for adding the variables? If you found significance, what is the strength of the effect? Explain your results for a lay audience, explain what the answer to your research question. Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style. Respond to at least one of your colleagues’ posts and comment on the following: Do you think the variables are appropriately used? Why or why not? Does the addition of the control variables make sense to you? Why or why not? Does the analysis answer the research question? Be sure and provide constructive and helpful comments for possible improvement. If there was a significant effect, comments on the strength and its meaningfulness. As a lay reader, were you able to understand the results and their implications? Why or why not? Required Readings Laureate Education (Producer). (2016g). Multiple regression [Video file].

Run the diamond regression with all variables simultaneously, then answer the questions:1) Based on the regression results, predict the market value of a diamond with the following characteristics:Weight = 1.5 CaratsColor Grade: EClarity Grade: VS1Cut Category: Good Submit answer rounded to the nearest dollar without commas or "$".2) What percentage of the market price behavior do the regression variables appear to explain?Enter your answer rounded to the nearest whole number without "%". (i.e.: 45.3% is entered as 45)Use the file below for this exercise:When done, include the the completed excel worksheet as well

WK 1 Discussion 1: Scarcity [WLOs: 1, 2] [CLOs: 1, 2, 4, 5] Scarcity is the starting point for studying economics. Resources are limited while human wants are unlimited. Prior to beginning work on this discussion, read Chelsea Follett’s article, Are Humans Prepared to Overcome Resource Scarcity in the Future? (Links to an external site.)Links to an external site., as well as Chapter 1 Section 1.2 in your textbook, and respond to the following: Explain what resources are.Evaluate why current resource scarcity is problematic.What future problems would result from scarce resources?Do you agree or disagree, and why, with Chelsea Follett about overcoming future resource scarcity? Recommend how to overcome present and future resource scarcity. Your initial post should be a minimum of 300 words. WK 1 Discussion 2: Coke Versus Pepsi [WLO: 4] [CLOs: 1, 2, 3] A change in quantity demanded (or a movement along the demand curve) is caused by a change in its own price while a change in demand (or a shift of the demand curve) is caused by a change in non-price determinants that include changes in consumers’ income, taste or preference, price of other goods, expected future price, etcetera. Respond to the following: If Coke’s price increases, what will happen to the demand or quantity demanded for Pepsi, all other things being equal?Explain whether it is a movement along the demand curve or a shift of the demand curve.If Coca-Cola develops a new technology that makes Coke tastier, what will happen to the supply curve and demand curve for Coke?Is the demand (curve or schedule) for Coke or Pepsi seasonally different? What is the relationship between Coke and Pepsi? Do they have the same demand curve or are they different? Explain your reasoning. Your initial post should be a minimum of 300 words.
