3. Present a complete record of the day-to-day listings of your stocks in a tabular form.

The following stocks I chose was XIU.TO, K.TO,IPL.TO, BTO.TO, PPL.TO, WCP.TO

** 4. For each stock, use your data to calculate and interpret:

a) the mean price

b) the median price

c) the standard deviation
