Question:Problem Set 1: The independent-samples t test

Research Scenario: A learning psychologist is interested in comparing the success of two different mnemonics (memorization methods) on performance in a memory task. He assigns students to two groups, one which learns and uses a language-based rhyming memory technique, and one which learns and uses a visual "method of loci" spatial memory technique. He then administers a memory task to each group of students. The students are scored based on the percentage of correct answers.

Using this table, enter the data into a new SPSS data file and run an independent-samples t test to test the claim that there is a difference in the percentage of correct answers between the two groups. Follow the directions below the table to complete the homework.
