(iii) Find the mean, median, range and standard deviation for the 2005 returns. (iv) Repeat part (iii) for the 2010 returns. (v) Compare the performance and risk of investment among the two periods. I have attached the data sets for 2005 and 2010 to be used in the question. All work (histogram, tables. Etc) must be done in Microsoft Excel. Also you must type the steps taken (showing work, formulas used) and required information into a Microsoft Word document for each answer. no reference needed.
