Description
a) What assumptions are required for an ANOVA to be valid in a design where participants
are randomly allocated to a number of different experimental treatments? How would you
assess whether these had been met?
What is meant by the concept of a priori power in regard to an experiment comparing two

Identify two methods that a researcher can use to increase experimental power while
keeping the risk of incorrectly rejecting the null hypothesis at 5%.
