Question

A cognitive psychologist is selecting which mnemonic technique will result in the best recall of 20 adjectives from a word list. Participants were randomly assigned to one of the four mnemonic conditions, with four participants in each group. Participants were given a different set of instructions in each condition to guide them in how to use the mnemonic technique and were then presented with a 20-item word list of adjectives. Participants were given two minutes to study the word list, then participated in a 30-second distraction task, and were then asked to recall the words from the list. What is the verbal null hypothesis ($H_0$) for this study?
