Question

I keep using EM2 - (EM)2/3 and I've been getting my answers for SS Between but now I'm seeing that the textbook says to do n(EM2-(EM)2/G) so I'm confused! Have I been doing it wrong yete getting proper answers?

A professor notes that many of her students take notes on their laptops, while others take notes using paper. She wonders if using a laptop is as effective as handwriting notes because typing allows students to take notes much faster. Although this increased speed does allow for more information to be written, it also does not require as much processing of the information. While taking notes by hand, students must process the information and decide what is important. To test this possibility, the professor obtains a group of 90 students and randomly assigns each student to use a different note taking strategy while listening to an hour long lecture. The groups were: Group 1: Handwritten notes Group 2: Take notes on a laptop Group 3: Take notes on a laptop, but instruct students that they should not record the lecture in as much detail as possible. Instead, they should try to write the main points. The day after the lecture, the students took a multiple choice exam over the content of the lecture. Use the SPSS ouput below to fill in the summary table values.
