Inferential and Descriptive Statistics

Lyrics & Music © 2017 by Greg Crowther
 
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]
