Measures
While many of our measures have been used in prior research, the core element of this study (EM) is a new construct. Fortunately, much groundwork for the
operationalization of the construct has been. This groundwork permitted us to

what we want to measure is exchange rate change related to USD.
Although the empirical result cannot support our theoretical expectation, we did not give up the expectation because we do know the insufficiency of the data which is used in regression analysis. If we have enough data, we might find the result which coincides with our expectation. Thus, we prudently conclude that oil price

4.1 Sampling
4.4.1 Target Population
All KU students in Anam campus is our target population.
4.4.2 Convenience Samples
Our team doesn’t know the probability that any KU students will be included in sample, so we did nonprobability sample method. Am
