Do make time to go through this excellent tutorial if you’re feeling a bit rusty on your stats! It’s written in R Statistical Software, but you don’t have to know R to go through it.

Topic - Preregistration
This will make more sense if you wait until I have uploaded my lecture and you’ve had time to have a look - however, it could be done independently too.
This is an activity that requires reading a very accessible article about preregistration of studies, and answering some open questions at the end. I would be grateful if you could post your responses in this Forum. The exercise is drawn from the Open Stats Lab website. As an extra exercise, try looking up a preregistered study here, check the preregistered hypotheses and see if the authors stuck to them.
Please read the exercise outlined below, and post your responses here.
Background:
If I were to accurately predict the outcome of the flip of a coin 10 times in a row, that would be very impressive. If I were to flip a coin 10 times, see what the outcome is, and then claim that I had correctly predicted the outcome, that wouldn’t be impressive at all. The same is true for predicting the outcome of a psychology experiment. If I predict the outcome of an experiment ahead of time, it lends credibility to the theory I used to derive my hypothesis.However, if I can only make an accurate prediction after I have seen the results of my experiment, then it really doesn’t suggest that my theory is correct at all. It merely suggests that I am good at explaining how the results of my experiment fit within my theory.
In this exercise, we want to consider the ways that the preregistration of hypotheses can improve psychological science.
