1. Find the bond yields of Turkey from 2010 - 2015 2. Find the official Interest rates of Turkey between 2010 - 2015 Calculate the mean, standard deviation, variance, covariance, and correlation of the variables. Then build a graph depending on the values of yields and interest rates. Build a second graph for values yield and interest rate in scatter plot (you will find this one in excel also.) Then show me whether there is a linear relationship or not PS: I want to see the data source. 1. Find the bond yields of Turkey from 2010 - 2015 2.
