As well as using the hypothesis testing to find out any significant differences in the variability of the depreciation of USD for the two other currencies.

We were underlying conditions and factors that caused these specific movements to happen. And also economic models with the sample population selected will be used to support the discussion and to analyses the reason for these fluctuations such as the inflation rate and interest rate.
