Visual versus Textual Learners Researchers wanted to know whether there was a difference in comprehension among students learning a computer program based on the style of the text. They randomly divided 36 students of similar educational level, age, and so on, into two groups of 18 each. Group 1 individuals learned the software using a visual manual (multimodal instruction), while group 2 individuals learned the software using a textual manual (unimodal instruction). The following data represent scores that the students received on an exam given to them after they studied from the manuals.
(a) What type of experimental design is this?
(b) What are the treatments?
(c) A normal probability plot and boxplot indicate it is reasonable to use Welch’s t-test. Is there a difference in test scores at the = 0.05 level of significance?
