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 studies from the manuals. Is there a difference in test scores at significance level 0.05?

GPA Versus Seating Location. A professor wanted to know whether there was a difference in students’ grade point averages (GPA) depending on whether they sit in the front half of the classroom versus the back half of the classroom. In a previous semester, a random sample of students was selected from the front of a classroom and another random sample was selected from the back of a classroom and each student’s current GPA was recorded.

An educational researcher wanted to know if in-class activities significantly improved students’ learning compared to traditional lecture only teaching methods. Ten students matched on GPA, Year in school, and academic major were randomly selected from the current student population. One student from each pair was randomly assigned to either the Lecture Only class or Lecture plus Group Activities class. At the end of the semester, students’ final exam scores were recorded and teaching methods were compared. Which type of statistical...

Edward wanted to know whether students’ attitudes towards the extra-curricular activities sponsored by EKU differed as a function of class year and gender. So Edward randomly surveyed 12 freshman, 12 sophomores, 12 juniors, and 12 seniors, with each class year sample having equal numbers of male and female participants. Each student was asked to rate their attitude of EKU’s extra-curricular activities on a 1 – 10 scale with 1 being totally negative and 10 being totally positive. This is a...
