Year Nominal Return(%) Inflation(%)
2012 0.2 6.9
2013 -16.0 7.0
2014 -14.0 7.5
2015 -42.5 11.8

a). Standard deviation of the nominal returns = {[(nominal return - average)^2]/n}^0.5

where n = number of observations = 6

Standard deviation = 35.32%

b). Real return r = (nominal return - inflation)/(1+inflation)

Average real return = sum of real returns/number of observations = - 2.91%

Calculations are, as follows:

Formula				r = (n-i)/(1+i)
Year	Nominal Return n (%)	Inflation i (%)	(n-A)^2	Real return r (%)
2012	0.20%	6.90%	0.001320	-6.27%
2013	-16.00%	7.00%	0.039336	-21.50%
