Accounting Analysis and Explanation of Johnson and Johnson & Pfizer

Goal: Due to the increasing demand of data analytics skills by employers, this project is intended to help students get a sense of data analysis by working with a set of simple data. Requirement: Choose two public companies in the same industry, and compare their last ten years net income by calculating their means, average growth rates, and standard deviations. In addition, create their time-series plots of net income to evaluate their pattern and behavior. Next, repeat the same analysis using return on assets. Last, explain in plain English what these numbers mean and what the plots suggest. What is the main takeaway of your analysis?
