Research Design Methods And Applications

 

Businesses often conduct research to maximize profits as well as to understand their competitive edge. There are a number of considerations when preparing and conducting research for a business – biases, reviewing credible sources, and ethical considerations. Throughout the research process it is important to recognize and remove personal biases in order to provide a balanced and thorough review. Another important consideration is to review and utilize sources that are reliable and provide objective information. It is also important to think about the ethics of your research. Being honest, respecting the integrity of data, and being objective help to ensure the credibility of research.

Utilizing the Internet, CTU Library, and your textbook, choose 1 example (or use one of those listed below) of unethical research in a business setting, and discuss the following:

Explain why research might be considered unethical.
Share your research topic and explain ethical considerations when conducting your research.

What test MSE do you obtain? (Hint: use set.seed (1); mtry=10 since we have 10 predictors in Carseats dataset and we use all of the predictors in the bagging approach).
2.5 Use random forests to analyze this data.
a) What test MSE do you obtain? (Hint: use set.seed(1); mtry=10/3 since we usually use 1/3 of the predictors when building a random forest of regression trees)
b) Use the importance() function to determine which variables are most important. Take a screenshot of your results.
c) Plots of these importance measures can be produced using the varImpPlot() function. Take a screenshot of your output.
d) So which variables are most important
