We have been doing a group project on the company Pfizer Pharmaceuticals. We are comparing Pfizer to Merck, Abbott, and the S&P.
Since no group evaluated their stock analysis, this assignment requires you to do so. I hinted that you need to standardize your data. This is important when comparing stocks that trade at different amounts (i.e., one company's stock is about $20, another about $100, and S&P is at $1200). For this assignment, use the data you obtained for Annual Report Part 5, standardize your data develop ONE (line) graph with all four data. Using ANOVA, compare the stock price (standardized) for each group at the end of each quarter and interpret the results of the analysis.
This solution computes for the Analysis of variance (ANOVA) for Pfizer, Merck, Abbott, and S&P. The statistical computation shows that "there is no significant difference between the stock prices of Pfizer, Abbott, Merck, and S & P". This computation is shows in the two (2) attached spreadsheet files.
