CHORUS:
Inferential and descriptive:
different stats with different rules
Inferential and descriptive:
different goals and different tools.
What's the average height of students in this room, whom I can measure?
Here you are describing data that you've got.
What's the average height of students living in Australia?
Now you are inferring something you know not.
[REPEAT CHORUS]
When reporting variation in descriptive information,
interquartile range may be employed.
When reporting variation in inferential information,
standard error of the mean may fill the void.
[REPEAT CHORUS]

to reject the null (to reject the null)
if its false indeed
Power is the probability
to reject the null (to reject the null)
if its false indeed
Uncertainty is the prerequisite to gaining knowledge and frequently the result as well.
Edith Hamilton (1867 – 1963)
… assuredly of all earthly conditions uncertainty is the most unblest …
Fanny Kemble (1809 – 1893)
…we have this opportunity to try to make meaning out of data ourselves, because frankly, data doesn't create meaning. We do.
Susan Etlinger (1962 - )
