Principles of Experimental Design

Lyrics © Mary McLellan
may sing to the tune of "Spongebob Squarepants Theme Song"
 

Make an experiment what do you do?
Control, randomize, repeat

Make an experiment what do you do?
Control, randomize, repeat

Make an experiment what do you do?
Control, randomize, repeat

 

Make an experiment what do you do?
Control, randomize, repeat

 

Randomly assign to the treatment groups
So you can claim the cause and effect
