One theory about the daily changes in the closing price of a stock is that these changes follow a random walk- that is, these daily events are independent of each other and move upward or downward in a random manner - and can be approximated by a normal distribution. To test this theory, collect the opening and closing prices of stocks from for your favorite company or brand.

Initial Post:

Choose your favorite company or brand and search finance.yahoo.com with that company name and "historical stock prices." Download the stock history for this company for the past 6 weeks by selecting the appropriate dates and clicking on "Download to Spreadsheet" at the bottom of page.
Calculate the daily change in the closing stock prices by taking the difference between the closing and opening price for the day. This is the daily stock change.
Calculate the mean and standard deviation of the daily stock changes by running the Descriptive Statistics in Excel Data Analysis. Share the summary table.
Consider the mean, median and mode (if it exists). Is your daily stock change distribution right skewed (median < mean), left skewed (mean < median), or symmetric (mean ≈ median)? What other considerations would you look at to determine whether or not this distribution is approximately normally distributed?
