A couple of important things to note:
Statistically Significant (Analytics) – means that the research “Math” shows something
happened. This is proven in one of two ways. Either the absolute value of the test statistics
that is calculated is greater than the critical value of the test usually found in a table OR the
p-value calculated from the test statistic is less than or = to a pre-determined risk amount know
as alpha (α), which unless otherwise stated is 0.05 or 5%.
Clinically Significant (real world) – means that what was found has relevance to the health
care practice. A study about an irrelevant topic (has little or no effect on patients would not be
clinically significant. To support this one needs to do additional research to determine if this is
the case.
Means are a measure of center and Standard Deviations and range are a measure of variability
or dispersal.
Opinions and what is expected should be evidence based, and thus supported
by outside research and cited
APA FORMAT
: Name the test, what variable/s and how they are computed. State the
statistical conclusion. Give the statistics (see example in Exercise for correct way to represent
these statistics) State the experimental conclusion or conclusions that the researchers came to.
