The last example is describing a within group design.
Within group design: When one set of participants are tested more than once and their scores are compared. It is also called 'repeated measures' because the researchers are repeatedly measuring the performance of each participant.
In the other cases different set of groups are used. So they are between group design.

CASE STUDY Cats or dogs—which is the better pet for relieving stress? To answer this age-old question, your DSC decided to test whether they should start a “Furry Friends” program for emotional support during exams using dogs or cats. To test the difference, they selected 40 random people who didn’t have a pet at home. Each person was randomly assigned to either a cat treatment or a dog treatment and asked to drop by the test room for 30 min...

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 21.4 with a standard deviation...

The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...
