Only if you are using inferential statistics. Most stats Kyle was talking
about are descriptive stats. And, (this is a technical point for Beth the OT
for her Biostat question) the 5% relates to the level of chance. For example,
if I find the mean salary difference between groups are statistically
significant, that indicates only that the difference in the two salaries
could be found by chance only 5% of the time. An infinitesimal distinction,
but important, nonetheless.
Another example is the almost perfect correlation between ministers
salary in New York State and wine production in California.
