Is this a random allocation?

Question

My sample is 11 classes, so i clearly have a problem becuase it is an odd number (i have two treatments). So i was wondering if this is random. Create two pieces of paper, each one written a type of treatment. Have all 11 teachers randomly select one of the papers so that each class has a 50% chance of getting a certain type of treatment. Is this a random allocation?

Answer 1

You have two problems. First is the 11 class allocation. This is not too difficult to work with statistically.

The other is randomness. You can actually become TOO random. Exactly why do you want random picks? To account for morning vs afternoon reponse bias? Once you figure that out, you can randomize as you wish
