For this activity, select a recurring quantity from your OWN
life for which you have monthly records at least 2 years (including
24 observation in dataset at least). This might be the cost of a
utility bill, the number of cell phone minutes used, or even your
income. If you do not have access to such records, use the internet
to find similar data, such as average monthly housing prices, rent
prices in your area for at least 2 years (You must note the data
source with an accessible link). Data can also be monthly sales of
some particular commodity. 1.4 Please do the descriptive analysis,
using the method of index number and Exponential Smoothing
individually. And try to explain the pattern you find. 1.5 Use two
methods you learned to predict the value of your quantity for the
next year (12 months). And make comparison with two results.
