I fear my data sample is too small to answer that, yet I have discovered a most interesting point.
Note: Percentages may not add up to 100 percent due to rounding of data samples.
Note that the two-sample test checks whether the two data samples come from the same distribution.
For a finite data sample, the mode is one (or more) of the values in the sample.
These results were confirmed when the analysis was repeated on a larger data sample.
Such intelligence was coming in at the rate of 20 million data samples per second, 24 hours a day.
In such cases, for a safe operation, the system has to be compensated for missing data samples.
Like everything else, it's all a matter of interpreting a mighty slim data sample, Skip.
The characteristics of the data sample can be assessed by looking at:
Also, one observation for New Zealand in 1951 moved the data sample's central tendency significantly away from what it otherwise would have been.
