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]
