We asked people what their favourite kind of chocolate was, white or milk, and how happy they were feeling at the start of the trial. Then we gave them a randomly selected type of chocolate to eat. At the end of the trial we asked them again how happy they were feeling.

This means we left it up to chance which group they ended up in. We asked them to reach into a bag and take out a ball. The colour of the ball decided what kind of chocolate they would be given.

]]> 2026-06-10 13:57:22 UTC https://padlet.com/ahuntermattacks/7kfyyzi4eyqw1dtg/wish/3948332607 Some things happened that we didn't expect... ahuntermattacks https://padlet.com/ahuntermattacks/7kfyyzi4eyqw1dtg/wish/3948337235 If you've been doing the sums as you've been going along you'll have noticed that after chocolate we had 371 participants whereas before we gave out chocolate we only have 358!


Our participants used stickers to give their answers, and we counted these stickers for our results. So where did the extra stickers come from? And how might they affect our results? Let us know what you think in the comments.


More people preferred milk chocolate than white. Do you think this could have had an effect on the results?


What do you think of randomisation? How can this make the trial fairer? Is there anything else we could have done to make it fairer?
