You performed a study investigating the effects of time pressure on performance on a verbal task. you had participants complete an anagrams task, where they had to unscramble some scrambled words. half of the participants were told that they would have to rush in order to get the anagrams completed, and the other half were told that they should have plenty of time to solve them all. the dependent measure was the number of anagrams solved. what type of test would you perform to examine whether the independent variable had a significant effect on anagram performance?
