A group of 20 people were asked to remember as many items as possible from a list before and after being taught a memory device. Researchers want to see if there is a significant difference in the amount of items that people are able to remember before and after being taught the memory device. They also want to determine whether or not men and women perform differently on the memory test. They choose ? = 0.05 level to test their results. For your convenience, I have prepared an excel file with this information titled: data_homework10_memory. Use the provided data to run a Two-way ANOVA with replication. A B C
