This paper by using statistic method discussed the main movements of the exchange rate between Australian Dollar against American Dollar (AUD/USD) and Chinese Yuan against American Dollar (RMB/USD) in the past 120 days.
The exchange rates data has been collected and analysed, presented by graphs to show the general trend of exchange rate between AUD/USD and RMB/USD for the past 120 days. The six research questions has been formulated and concluded. We use the statistical techniques such as the regression equation to work out the relationship between AUD/USD and RMB/USD. 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.

Due to the limited time, cost spending thus the quality of research and analysis will be limited. In addition, data is collected from publicity source as Internet, thus the immediate and accurate important may not reached and consequence the report will be attained with not deep analyzing with real situation. Finally, because of specific characteristics of exchange rates, we might not have enough of specialize to cover the inside with many factors could impact on the exchange rates.
