Abstract

Here we analyze several economical variables which have been affected by the period of COVID-19. In particular, EUR/US exchange rates are addressed. Oil prices have been very volatile and many other economical variables have changed their behavior. We show by application of statistical tests for normality, including QQ-plots and Shapiro-Wilk that exchange rates of EUR to US from 10/13/2019 to 4/9/2020 are substantially deviating from normality and outliers are present. It is clear that changes to the economical variables have been of interest.
