Stationary Test (Unit Root Test) Nelson and Plosser (1982) argue that almost all macroeconomic time series one typically uses have a unit root. The presence or absence of unit roots helps to identify some features of the underlying data generating process of a series. In the absence of unit root (stationary), the series fluctuates around a constant long-run mean and implies that the series has a finite variance which does not depend on time. On the other hand, non- stationary series have no tendency

The mean is found by getting a total of all the ounces in the bottles. The ounces total, 446.10 and divided by the number of bottles of 30 is 14.87. The median is the midpoint of the data array which is when the data is sorted by size, the median is 14.8. The standard deviation is found by taking each value in the chart and subtracting the mean and squaring
