a.Obtain the arithmetic mean, geometric mean, harmonic mean, median, mode, range

a.Obtain the arithmetic mean, geometric mean, harmonic mean, median, mode, range, MAD, variance, standard deviation, semi variance, skewness, kurtosis and excess kurtosis of each.
b.Obtain the covariances and coefficients of correlation between all possible combinations e.g, ( Rit, Rjt), (Rit, Rmt),(Rit, Rft), (Rjt, Rmt), (Rjt, Rft) and (Rmt, Rft)
c.Change the data into price-relatives (i.e. add “1” to the return data) and recomputed the geometric mean using geometric mean return formula.
